jinternalframe

问题 I have a JDesktopPane and want to display JInternalFrames in a grid style without overlaying frames. The dymensions of the frames will vary so their location should be assigned dynamically. I could store the coordinates of the last placed frame but frames can be moved, minimized or closed.. Is their an easy way of placing internal frames in a tidy way? e.g., using a Layout? 回答1: Here's an example that may offer some guidance. It uses setLocation() and an offset. 回答2: The DesktopManager class

问题 This is my source code. I can't get my JInternalframe to the front. I have tried many codes out there, but nothing worked. private void jMenuItem3ActionPerformed(java.awt.event.ActionEvent evt) { boolean b = true; JInternalFrame[] j = jDesktopPane1.getAllFrames(); no = new NewOrder(); for (JInternalFrame Ji : j) { if (Ji.isShowing()) { b = false; break; } } if (!b) { no.requestFocus(true); } else { dm = jDesktopPane1.getDesktopManager(); jDesktopPane1.add(no); dm.setBoundsForFrame(no,

问题 I am trying to use DefaultDesktopManager (or a sub-class of this) to control the moves out of JInternalFrames from a desktop panel. I can prevent that a frame is moved out of its desktop pane, however, when I minimize the internal frame I get: Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at javax.swing.RepaintManager.getVolatileOffscreenBuffer(RepaintManager.java:965) at javax.swing.RepaintManager$PaintManager.paint(RepaintManager.java:1398) at javax.swing

I tried adding it to a JOptionPane.showInternalMessage(...), but since I want to make the dialog to go away automatically after 3 seconds, this would not work, as the the JOptionPane dialog would just stay there until someone clicks OK. Any idea? Many thanks. 回答1: Yes you have to add it to a container in which you want it

问题 How would one go about getting the z order (layer depth of ) all the JInternalFrames inside a JDesktopPane. There does not seem to be a straight forward way for this. Any ideas? 回答1: Although I haven't tried this, the Container class (which is an ancestor of the JDesktopPane class) contains a getComponentZOrder method. By passing a Component which is in the Container , it will return the z-order of as an int . The Component with the lowest z-order value returned by the method is drawn last,

问题 I working with JDesktopPane and creating multiple JInternalFrame objects. When I minimize all and maximize any one of them, the opened frame covers all minimized frames. How to make all minimized frames visible? 回答1: By default the internal frame is maximized to take all the space of the desktop. This behaviour is relatively easy by change by customizing the DesktopManager . For example: import java.awt.*; import javax.swing.*; import java.beans.PropertyVetoException; class

问题 How to Disable/Enable JFrame components when JInternalFrame isVisible inside JFrame / JDesktopPane ? For example, make every JInternalFrame1 visible on the JDesktopPane (desktop pane set on the JFrame ) all frame components like JMenuBar / JButton /etc. set disabled. Have a solution? 回答1: If you have a reference to all your components, the best shot is to write a simple method that would disable everything (more or less like a state machine).
