Description

Hi,

I wanted to use the new initialSize parameter of the WBoxLayout::setResizable() method. It works as expected, but if a widget is hidden the layout does not resize other widgets in this layout. The following screenshots demonstrate the problem:

Screenshot shows the initial state of the application
Screenshot shows the hidden bottom view without using initialSize (every thing is correctly rendered)
Screenshot shows the initial state of the application with using initialSize
Screenshot shows the error when the bottom view is hidden

Regards,

Stefan

Hi,

attached you will find a simple test app which can be used to reproduce the error.

Push the Hide-Button several times and the bottom view "More details" will be hidden/showed and everything is rendered fine
Push Use InitialSize-Button once
Now the pushing the Hide-Button will produce the layout problems...

Also the resize handle is not correctly rendered?

Stefan

Hey,

I fixed the (two) issues:

the resize handle (bar) is now correctly hidden for this case
initialSize being picked up as a fixed size when there is no more resize handle controlling it's size
removed a comment that said that the old code "wasn't entirely accurate" :-)

Thanks for the test case!
