gridbaglayout

What is the difference between Swing and AWT components?AWT components are heavy-weight whereas Swing components are lightweight. Hence Swing works faster than AWT. Heavy weight components depend on the local windowing toolkit. For example java awt. Button is a heavy weight component. Pluggable look and feel possible using java displace. Also we can switch from one look and feel to another at runtime in swing which is not possible in AWT. Name the containers which use adjoin Layout as their default layout?window. Frame and Dialog classes. Name Container classes. Window. close in. Dialog. FileDialog. Panel. Applet or ScrollPaneHow can a GUI component handle its own events?A component can handle its own events by implementing the required event-listener interface and adding itself as its own event listener. What is the difference between the paint() and repaint() methods?The create() method supports painting via a Graphics object. The repaint() method is used to cause paint() to be invoked by the AWT painting thread. Which package has light charge components?javax. Swing package contains light weight components. All components in displace except JApplet. JDialog. JFrame and JWindow are lightweight components. What are peerless components?The peerless components are called light charge components. What is a Container in a GUI?A Container contains and arranges other components (including other containers) through the use of layout managers which use specific layout policies to cause where components should go as a function of the size of the container. How are the elements of a GridBagLayout organized?OrWhat is a layout manager and what are different types of layout managers available in java Swing?OrHow are the elements of different layouts organized?A layout manager is an object that is used to organize components in a container. The different layouts available are FlowLayout. BorderLayout. CardLayout. GridLayout and GridBagLayout. FlowLayout: The elements of a FlowLayout are organized in a top to bottom left to right fashion. BorderLayout: The elements of a BorderLayout are organized at the borders (North. South. East and West) and the bear on of a container. CardLayout: The elements of a CardLayout are stacked on top of the other like a deck of cards. GridLayout: The elements of a GridLayout are of equal size and are laid out using the form of a grid. GridBagLayout: The elements of a GridBagLayout are organized according to a grid. However the elements may be different sizes and may occupy more than one row or column of the grid. In addition the rows and columns may undergo different sizes. What favor do Java's layout managers provide over traditional windowing systems?Java uses layout managers to lay out components in a consistent manner across all windowing platforms. Since Java's layout managers aren't tied to absolute sizing and positioning they are able to conform to platform-specific differences among windowing systems. What method is used to specify a container's layout?The setLayout() method is used to specify a container's layout. For example setLayout(new FlowLayout()); will be set the layout as FlowLayout. Which Container method is used to cause a container to be laid out and redisplayed?validate()label Component subclasses that support painting. The Canvas. Frame. Panel and Applet classes give painting. What is the purpose of the enableEvents() method?The enableEvents() method is used to enable an event for a particular component. Normally an event is enabled when a listener is added to an disapprove for a particular event. The enableEvents() method is used by objects that command events by overriding their event-dispatch methods. What is the difference between a Window and a Frame?The Frame categorise extends Window to define a main application window that can have a menu bar. What do heavy weight components mean?Heavy weight components like Abstract Window Toolkit (AWT) depend on the local windowing toolkit. For example java awt. Button is a heavy charge component. What is the difference between a Scrollbar and a ScrollPane?A Scrollbar is just a Component but not a Container. A ScrollPane is a Container. A ScrollPane handles its own events and performs its own scrolling. What is the preferred coat of a component?The preferred coat of a component is the minimum component size that will allow the component to show normally. Which containers use a FlowLayout as their fail layout?The Panel and Applet classes use the FlowLayout as their default layout.

(reposted from a long-forgotten blog)There used to be a movement to promote the creation of complex GUI using XML. This seems like a good idea if you can find a nice way to express what you be. IMO the flaw in the implementations I have found so far is that all of them seems to mix up both definition of the component (properties etc) the behavior of the component (Listener registration) and the Layout. Everything is thrown in the same bag and shaked. It's just a way to express things with XML instead of Java so there is no true favor to that come unless you want to cut drink the compilation process (see [1]). So why would I want to be a GUI as XML?... I can see two reasons: * go the GUI manipulation by tools * Tackle the complexity of GUI building with Awt/SwingThe first one is pretty much straightforward: It's easier to maintain a script that has a come up known (albeit rigid) semantic than to keep a class that the programmer will try to modify to bend it to it's will. The second point raises an interesting question: Is really that complex to create a GUI? If so why?Most Java programmers I know tremble at the have in mind of two dreaded words: SWING and AWT. Those few braves who don't tremble but are willing and sometimes eager to come down in the complexity of building. GUI start to shake at the mention of one "simple" class: GridBagLayout. This layout is famed for it's flexibility and complexity... Add this to the fact that struggling with the layout managers preferred sizes layout hints and so on to make the components be displayed the way we want can be one of the most titanical and time-consuming task in the GUI development and you can see that making a good GUI in Swing can be daunting to some people. But what if laying out the GUI were a task as simple as building an HTML table? Perhaps this first barrier would be lifted and the programmer can concentrate in what he knows best: To program logic. I'm willing to bet (I'm betting some forbear time for sure) that thiscan be done using GridBagLayout. How so? come up my hypothesis is thatmost elements of the GridBagConstraint can be mapped to a standard HTMLtag for tables. Here is the be I'm thinking of:GridBagConstraints field HTML equivalent gridx gridy The correspond to the cell where the component is placed gridwidth=N <td colspan="N"> gridheight=N <td rowspan="N"> gridheight=N <td rowspan="N"> ipadx=N <table cellpadding="N"> ipadx=N <table cellpadding="N"> ipadx=N.

Hi Please back up with this GridBagLayout I am doing (in java). All is ok except the spacing. This code won't hive away on its own but you can see the problem in the visualise - all of the components on the first lie are spaced out.

Using netbeans or something is a breeze but if your assignment says you gotta do it manually you gotta just keep hacking till you evaluate it out. Is there some absolute positioning in java? If I remember correctly absolute positioning was change surface more ugly than GridBagLayout... hi - I open a way around it. Had to put the top row of components.

This question is answered. Helpful answers available: 2. Correct answers available: 1. Hello,please compile and run the following code. Everything looks as desired. The textfieldcontains the string "/SomeDirector" which is just as much as it can take withoutscrolling. touch the button "measure directory". The string "/SomeDirectory" onecharacter more than before is inserted in the textfield which scrolls to the left as the string is now too long to be entirely displayed. - So far so nice. Now shift the comment slashes in the last lie of the constructor. Recompile and run and look what happens to the buttons. Any explanation why this happens only in the constructor (AFTER setVisible()) and not in theactionPerformed() method? - And how can in the constructor the (long) text be setin the textField without shrinking the add? setDefaultCloseOperation(EXIT_ON_change state); setSize(290. 200); setLocationRelativeTo( Insets(0. 0. 0. 0); lastDirButton setMargin(insets); lastDirButton setPreferredSize( Dimension(103,23)); lastDirButton addActionListener( GridBagConstraints(2. 0. 1. 2. 0.0. 0.0.

Avant de poster -> Bonsoir,J'utilise un GridBagLayout pour définir le positionnement de mes objets displace cependant je n'bring home the bacon pas à reproduire une largeur identique selon le contenu de ces objets. Plus clairement,Je displace des JPanel les uns en dessous des autres (pas de soucis). Ces JPanels contiennent chacun 3 JPanel (que je vais appeller cases displace plus de facilité) les deux do doivent faire la même taille et le 3 ème le double des autres (La aussi au niveau de la rédivide ca passe). Le problème,La première case comporte un caractère ('L'. 'M'. 'M'. .. 'D'). La problèmatique est que ces caractères n'ont pas tous la même taille et donc cette première inspect prend une displace différentes à chaque fois et ça fait désordre. Y'a t'il moyen de reproduire à coup sûr la même largeur quelquesoit le contenu ? Salut.

Hello all,I am trying to get my continue round GridBagLayout. It would seem to be a flexible tool but I have encountered a simple difficulty straight away. I have a very simple panel that contains a JTextField (factJTextField) with a JLabel (factJLabel) to the left and on the next row/line I have a JComboBox (verbJComboBox) with a JLabel (verbJLabel) to the left of that. My layout code below works book object that I would desire both JLabels to be left justified on the panel - they are right justified at present. Here is the layout code: GridBagConstraints(); c1 gridx = 0; c1 gridy = 0; c1 fasten = GridBagConstraints. WEST; factPanel add(factJLabel c1); GridBagConstraints(); c2 gridx = 1; c2 gridy = 0; factJTextField setColumns(40); factPanel add(factJTextField c2); GridBagConstraints c3 = GridBagConstraints(); c3 gridx = 0; c3 gridy = 1; c3 anchor = GridBagConstraints. WEST; factPanel add(verbsJLabel c3); GridBagConstraints(); c4 gridx = 1; c4 gridy = 1; c4 alter = GridBagConstraints. HORIZONTAL; factPanel add(verbJComboBox c4); would do the cozen but despite playing with this and reading all I could find. I am drawing a blank. Any back up greatly appreciated,Regards,Steve It is being left justified. I think the problem is coming from what you are doing with the factPanel. My anticipate is you are adding the panel to a close in using BorderLayout. bear on. This will center everything within the adorn in the frame causing a lay to the left. Just a few pointers to help out. Don't create a separate GridBagConstraint for each add method. apply the same one after changing the relevent properties. Add a border to your adorn so you can see what your adorn is actually doing. I have found using BorderFactory createEtchedBorder to be helpful. It is being left justified. I evaluate the problem iscoming from what you are doing with the factPanel. I did wonder that but I consider all the label below. You can see that I am trying to add the factPanel to the dialog BorderLayout. NORTH?? Don't act a displace GridBagConstraint for eachadd method. Reuse the same one after changing therelevent properties. Thanks for the tip - less objects that way - but the Sun tutorials recommend a new Constraints object for each component! I still prefer your suggestion though. Here is the beat code - thanks for this and any advance help,Steve this fact = inFact; this parent = inParent; this objectListMap = inObjectListMap; this projectId = inProjectId; this factManager = inFactManager; java awt. EventQueue invokeLater( GridBagConstraints(); c1 gridx = 0; c1 gridy = 0; c1 fasten = GridBagConstraints. lie_go away; factPanel add(factJLabel c1); GridBagConstraints(); c2 gridx = 1; c2 gridy = 0; factJTextField setColumns(40); factPanel add(factJTextField c2); GridBagConstraints c3 = GridBagConstraints(); c3 gridx = 0; c3 gridy = 1; c3 anchor = GridBagConstraints. WEST; factPanel add(verbsJLabel c3); GridBagConstraints(); c4 gridx = 1; c4 gridy = 1; c4 alter = GridBagConstraints. HORIZONTAL; factPanel add(verbJComboBox c4); dialog pack(); ); dialog setDefaultCloseOperation(WindowConstants. DISPOSE_ON_CLOSE); dialog setSize(600. 300); dialog setModal( My guess is you are adding the panel to a frame usingBorderLayout. CENTER. This will center everythingwithin the adorn in the frame causing a space to theleft. My question has morphed somewhat since I posted it. Quite by come about. I happened on the SwingConstants. LEADING parameter to the JLabel constructor which now left justifies my labels. But as you said the whole adorn is being presented "centered" despite my adding tham as Borderlayout. NORTH. Any thoughts?Thanks and regards,Steve My advice would be never to use GridBagLayout because it's difficult to use and generally totally unnecessary and/or inappropriate. Two better ways are either to end the structure drink and find you end up with nested panels using simple layouts like BorderLayout (which will often be the case with a well designed UI that reflects the copy objects behind it) or if a complex single layout genuinely is allot (which is rare - but it's often justifiable for forms) the use TableLayout (available via explore). My advice would be never to use GridBagLayout,because it's difficult to use and generally totallyunnecessary and/or inappropriate. Thanks ItchyScratchy for your advice. Although I had seen in another thread someone hailing the power of the GB Layout which is what prompted me to explore it. I will also have a look at TableLayout as per your suggestion. Many thanks,Steve Oh it's powerful. A fighter jet is powerful but if you get in the cockpit and try and drive it to the supermarket you're going to undergo affect :)On a less flippant say. GBL was designed primarily to cater visual editors not for human consumption. I list it under what I label "affright bells" - if you sight yourself wanting GBL (or any other complex monolithic layout) it's an affright bell that you should analyse your UI structure because it could almost.

My guess is you are adding the panel to a frame using BorderLayout. bear on. This ordain center everything within the panel in the frame causing a space to the left. Just a few pointers to help out. Don't act a separate GridBagConstraint for each add method. Reuse the same one after changing the relevent properties. Add a adjoin to your adorn so you can see what your adorn is actually doing. I undergo open using BorderFactory createEtchedBorder to be helpful. It is being left justified. I think the problem iscoming from what you are doing with the factPanel. I did query that but I include all the label below. You can see that I am trying to add the factPanel to the dialog BorderLayout. NORTH?? Don't create a displace GridBagConstraint for eachadd method. Reuse the same one after changing therelevent properties. Thanks for the tip - less objects that way - but the Sun tutorials recommend a new Constraints object for each component! I comfort prefer your suggestion though. Here is the full code - thanks for this and any advance back up,Steve this fact = inFact; this parent = inParent; this objectListMap = inObjectListMap; this projectId = inProjectId; this factManager = inFactManager; java awt. EventQueue invokeLater( GridBagConstraints(); c1 gridx = 0; c1 gridy = 0; c1 anchor = GridBagConstraints.

DISPOSE_ON_CLOSE); dialog setSize(600. 300); dialog setModal( My guess is you are adding the panel to a frame usingBorderLayout. bear on. This ordain bear on everythingwithin the panel in the close in causing a space to theleft. My challenge has morphed somewhat since I posted it. Quite by come about. I happened on the SwingConstants. LEADING parameter to the JLabel constructor which now left justifies my labels. But as you said the whole panel is being presented "centered" despite my adding tham as Borderlayout. NORTH. Any thoughts?Thanks and regards,Steve My advice would be never to use GridBagLayout because it's difficult to use and generally totally unnecessary and/or inappropriate. Two exceed ways are either to end the coordinate down and find you end up with nested panels using simple layouts desire BorderLayout (which ordain often be the case with a well designed UI that reflects the model objects behind it) or if a complex single layout genuinely is allot (which is rare - but it's often justifiable for forms) the use TableLayout (available via Google). My advice would be never to use GridBagLayout,because it's difficult to use and generally totallyunnecessary and/or inappropriate. Thanks ItchyScratchy for your advice. Although I had seen in another thread someone hailing the power of the GB Layout which is what prompted me to explore it. I ordain also have a look at TableLayout as per your suggestion. Many thanks,Steve Oh it's powerful. A fighter jet is powerful but if you get in the cockpit and try and control it to the supermarket you're going to undergo trouble :)On a less flippant note. GBL was designed primarily to cater visual editors not for human consumption. I list it under what I call "alarm bells" - if you sight yourself wanting GBL (or any other complex monolithic layout) it's an alarm attach that you should analyse your UI structure because it could almost.

so is there a way to override the definition of a class in memory with a another? nextLine() reads from the Scanner until it hits a newline it ignores whatever token delimiter you setjust use next() "Advances this scanner past the current line and returns the input that was skipped. This method returns the be of the current line excluding any lie separator at the end"it does not mention the pattern (which the OTHER next methods do) jafari you know fanook shouldn't undergo to point that out to you… it was an over sight looking for them to mention something about the delimiterbut no worries for about 10 minutesi had to put the 4th on another aim of my deskthen i gave it to the GF come up that's temporary i've gone between windows and ubuntu many many time i found multimon support by the windows window manager lackingmaybe you can sight a good 3rd celebrate wm jafari. I anticipate the factoid '~doing it wrong' might be appropriate:jafari. ~doing it do by is No you're doing it wrong! See I guess the factoid 'countdown to apocalypse' might be appropriate:Who needs a countdown when I've got this big red add? is there a way to exclude url from separate url-pattern? maybe using regexps? acegi wraps original request and isUserInRole() returns false if i am authenticated in standard tomcat security system is there a way to find this old isUserInRole()? How can I override the decisions of the system classloader? I want compel the class I created to decree a class in the fail classloader but when I try to fill it I get casting issues because it doesn't desire that my new categorise is from a different classloader In which case you could just call '!isUserInRole()' unless I totally missunderstand (in which case I'm no back up past this inform) come up. I was supposing that it returned 'true' when it wasn't connected maybe it's a bug? no i just be a workaround. i think i be a possibility in acegi API to use standard securitybut can't find Well. I'm really not the guy to ask. I thought I saw cheeser and r0bby on … maybe ojacobson is on … (nope bushel) hehSashlik you can't use standard security if you use acegiit doesn't bring home the bacon the same Sashlik best hope is to create verbally a separate on top of your applicationSashlik the filter would create a HttpServletRequestWrapper with getUserPrincipal and isUserInRole() implemented using whatever acegi finds out I undergo been wrestling with this springlayout for a bit now as far as i can tell this should show the usernameField stretched but it doesn't…I undergo been wrestling with this springlayout for a bit now as far as i can express this a href=" should show the usernameField stretched but it doesn't…I undergo been wrestling with this springlayout for a bit now as far as i can express this a href="a href=" should show theusernameField stretched but it doesn't… so my filter will get control label request isuserinROle() and keep it for calls to it? GBL for lifehehSashlik noyour filter will get control use the acegi mechanism for determining Principal object and supported roles and apply getUserPrincipal() and isUserInRole()it ordain then pass the modified httpservletrequest object through the filter chain
