[CLOSED] close window when its parent is not visible anymore

[mirwais]

Hi,

I have a Panel inside a TabPanel. When the user clicks a button, a window is displayed.
How can I automatically close the window when its parent is not visible anymore. Which event do I need to handle?

thanks.

Yuo can use Hide event of Panel and hide Window in that event handler

Hi Vladimir,

some of my pages exemplify a high degree of nestedness, so what happens is that for the topmost panel (inside a tab panel or card layout) the hide event gets triggered but the nested panels know nothing about it. can i somehow notify them automatically that they are being hidden or do i need to implement my own event notification mechanism?

thanks
