project on Linux platform using the QT GUI, and contains several widget, use one of the QT QX11EmbededContainer widget embeds a written using Java Swing application form. Unfortunately, as long as the operation over Swing window ( even a mouse click ) , other widget can not receive keyboard events, such as the ListViewItem in another widget click Rename, has been in a state of waiting for input , keyboard input can not be displayed , but later found Swing all keyboard events are snatched away . If the test is more, occasionally by Xlib: unexpected async reply error message , and then hang the process of death . These issues only keyboard and mouse operation is no problem , if the other widget under the mouse right- click pop-up context menu , and then rename the class action touches the keyboard events can take it over .

ask you in improving the design of the next have any suggestions ?

recommended QProcess open java Swing do the procedure, so it will not hang.

If you can intercept java drawing event , I suggest java generated images directly into the Qt controls drawn from this space will java widget Qt's time to pass to java

I guess you have an open java program, a program where you input-output system was taken over by the java virtual machine , just like you open a modal dialog Like modal dialog message loop , took over all events , other forms of control can not be obtained , such as modal dialog only quit, other forms can be executed.

According to this idea , when you pop the java program , you let other form is not enabled , when the java program exits, and then enabled. So there is no conflict

Oh, both sides need to interact , or else do not need to embed the form.
just opened if not grab the mouse without clicking , and later robbed .
now plan on the basis of not saved ?

this shows that it was your focus into the java program that took over the ah , you should change your java program , it becomes " non-modal dialog " , or to the adoption of inter-process communication to solve the .
