Q Virtual Keyboard (XTestFakeKeyEvent) running within other Qt App. Focus problem?

[taraj]

Hello,

I have been using the following keyboard as a standalone application

http://qt-apps.org/content/show.php/QVKeyboard?content=77983

and it works great.

I wish to integrate this application into an exisiting product. I have a toolbar (QWidget) with buttons and edit boxes, i also have a display (QWidget), both are separate classes that are stared up in main() with 'new'. On the toolbar I have a QToolButton that when i press i wish to activate the qvkeyboard, when i press again i wish to close the qvkeyboard. I have attempted to do this 2 ways, both have problems though.

1.Use QProcess which calls proc->start("./qvkeyboard"). This works and qvkeyboard is able to be used/interacts with QLineEdit etc on the toolbar that the QToolbutton is on. Problem I have is that when i press the QToolButton again to close the qvkeyboard it won't. I have tried proc->kill and proc->terminate and it does nothing. Is there a way to send a signal/slot to a proc, or a message somehow?

2. I have intergrated the qvkeyboard code into my existing produce (called it KeyPadwindow). I create it with

KeyPadwindow = new Q_KeyPadwindow(0, Qt::FramelessWindowHint|Qt::WindowStaysOnTop)
at system start up then use

KeyPadWindow->show()
When the QToolButton is pressed
This show command opens the KeyPadwindow but it will not interact with the QLineEdit boxes in the toolbar. Do i need to get focus? Does the XTestFakeKeyEvent only send fake key to application outside the one that the code is being run?

I think that instead of using XTestFakeKeyEvent that i could use signals/slots but i would need to create a QKeyEvent for all the keys on the keyboard and this seems a messy way. Also how do i determine where the focus is between my 2 widgets (toolbar and display)? I need to be able to send key presses to both depending on where the focus is.
Depending on the key pressed can the focus be changed between the two? I don't really understand QFocus...


Hope that makes sense and some kind person can help

cheers,

I don't understand: do you use the virtual keyboard as a QProcess or do you use it inside your code?

I have tried it both ways, as a QProcess and as integrated inside the code (not at the same time)

proc->kill now works, not sure why it didn't before, but i would much prefer to integrate it into the code rather than a QProcess but it doesn't seem to get the focus for the widgets correct when inside the code?

Thanks

You didn't provide any details to the code so its hard to say...
