Hi there,

I am using BlackBerryGameCanvas of the 4.7 API to paint a custom textfield periodically. Now when a key on the virtual keyboard is held down and the special character window pops up, the part of the pop-up window that lays on the canvas gets drawn over. To prevent this situation I thought stopping the painting action temporarily might help. Is there a way to determine whether such a pop-up window is visible?

Many thanks in advance...

Try to use:

Ui.getUiEngine().getActiveScreen()

Thanks for heading me to the right direction.

Although not very clean, I came up with the following solution: I've created a custom class which extends NullField. When this custom class is added to the ActiveScreen, its onObscured method is called everytime the special character pop-up window appears.

I mean to check via instanceof the current active screen.

Make a script that gets name of class instance for special characters popup screen.

I think it is net.rim.device.api.ui.container.PopupScreen class.

So, you can do the following:

Screen activeScreen = Ui.getUiEngine().getActiveScreen();

if (activeScreen instanceof net.rim.device.api.ui.container.PopupScreen) {

     // special characters popup screen is displayed

}

You can do this check for example in onObsucred() event handler
