I am having a functionality which when the event occurs the JFrame pops up and if we click on that Frame it will open the corresponding frame, but the issue is when I am not clicking the popped up frame when the event occurs, if another event comes its displays the frame in the taskbar in a blinking state but not in an open state, I want to display the frame as it is without the frame blinking in the taskbar???? Any suggestions??? 回答1: I

问题 I have some questions regarding JFrame. Here's the scenario: I have made some object classes in java and I want to make the GUI for these objects. So i created 2 JFrames. One JFrame manipulating these different classes and the other JFrame manipulating the first one. The first JFrame i'll call it "TypesGUI".

问题 I am in a situation where I create a frame FrameB from my main frame FrameA . When the user is working on FrameB I would like it to be on top of FrameA even when the user accidentally clicks on FrameA . 回答1: Do you have to use a JFrame? If you use a JDialog instead of a JFrame and assign FrameA as the owner of the dialog through the constructor it will always remain on top of the frame. (Example: How to set the JFrame as a parent to the JDialog) Otherwise you can use setAlwaysOnTop() from the

Basically I have my MainWindow, when I press a button a new window should appear named PartSelectionWindow that contains a JTable (the JTable is filled out with a custom table model). Then I select a row and press ok to go back to the MainWindow and work with the info selected. Here's the problem: If I use a JFrame for the PartSelectionWindow, after the window is closed the code execution does not continue in the MainWindow

问题 I have done a little research online with no luck, and I cant seem to see a question on SO similar to this. I wanted to know if its possible to place a windows program to fit inside a jFrame or jWindow. The particular example I had in mind was if I were to create a jFrame, can I spawn a windows program to open (i.e. cmd.exe) and embed that window within my jFrame somewhere. Hopefully the following image depicts what Im trying to acheive. 回答1: This has been asked before several times on this

问题 Below I included two of the classes in my Java program (Launcher and Controls). In the both classes, they create a JFrame, draw a background image, and add lines of text. I have looked at the code over and over, but for some reason the background image and the line of text are not appearing in the second class (Controls). Could anyone please explain to me why this is happening? Launcher Class: import hungerGames.Display; import hungerGames.RunGame; import hungerGames.input.InputHandler;
