问题 How does one push a JInternalFrame to the top of all the frames in a JDesktopPane? 回答1: Read the JInternalFrame API and follow the link to the Swing tutorial on "How to Use Internal Frames" where you will find a working example of how to "select" the active internal frame. 回答2: try grabFocus() and requestFocus(). One of the should work. I personally used only requestFocus(). 回答3: In this example, a javax.swing.Action is used to select frames from a menu. 回答4: The OP has noted that setSelected

问题 I need to implement zoom for a JDesktopPane contained in a JScrollPane . I have had prior success zooming by overriding the paintComponent(...) method and calling scale(double,double) . This is not working properly: the JInternalFrame 's and JPanel 's scale as intended, but the MouseListener 's for the JLabel 's and such register at the pre-scaled locations. What can I do? Thank you for reading. 回答1: ScaledPanel shows how to scale mouse coordinates using explicit transformation methods:

I am creating a desktop application using the JDesktopPane. I'm almost complete, but when I press ctrl + alt + del , it leaves my application. How can I prevent that action? Fact is Alt + Ctrl + Del never actually entering your application. Os traps Alt + Ctrl + Del before it is send to your application. So you can't trap it. sabbour Alt + Ctrl + Del cannot be overridden. It is a security feature. Itay Maman You cannot do that. The behavior of Alt + Ctrl + Del is enforced by the operating system, for good reasons: it makes sure that you can always bail-out of a faulty application. http://www

How do I open a JInternalFrame centered in a JDesktopPane?

由 孤街醉人 提交于 2019-11-30 20:33:13
I am adding a bunch of JInternalFrame s into a JDesktopPane , as the user selects to open various features through the menus. But I would like the internal frames to open centered in the desktop pane, as opposed to the upper left, where they seem to default. How can I specify that the JInternalFrames open centered, or move them to the center after opening? jDesktopPane.add(jInternalFrame); // jInternalFrame is not centered! For reference, here is the solution I used, based on dogbane's advice: Dimension desktopSize = desktopPane.getSize(); Dimension jInternalFrameSize = jInternalFrame.getSize(

Preventing JInternalFrame from being moved out of a JDesktopPane

When I have a JInternalFrame in a JDesktopPane, the JInternalFrame is movable (which is good). However, it's possible to move it outside of the visible scope of the JDesktopPane (which I'm not so fond of) To see for yourself, here's some sample code: public static void main(String[] args) { JFrame frame = new JFrame("JDesktopPane"); JDesktopPane tableDisplay = new JDesktopPane(); JInternalFrame internalFrame = new JInternalFrame("JInternalFrame",true,true,true,true); internalFrame.setContentPane(new JLabel("Content")); internalFrame.pack(); internalFrame.setVisible(true); tableDisplay.add
