[Solved] How to hide and show a mainwindow?

[Eddy]

@jim_kaiser
it is possible to use hide() in the constructor of a QMainwindow class.
I tested it using a singleshot timer too.

you're right asking where Leon uses his show() function, probably this one is called after the hide() function.

Thanks for the clarification about the hide() in the constructor. Assumed there might be events from the desktop which the main windows reacts to after the construction and just thought its a bit iffy.

Hi,

by default each widget is hiodden, unless it has a visible parent. So hide in the constructorn is not needed. But mostly, the main contains a show call, remove that and it is hidden.

Hi Gerolf,

You're right it's hidden unless you show it first.

But what Leon wants is to use a mainwindow and click a button to hide it. Hiding seems not to work on his system. That's why i suggested to use a minimal working example because we don't have code to look at.

Ok so probably it was wrong to put hide(); at the constructor.. Putting it in a void function will work..
I made an example that hides both the dialog and the mainwindow :) ("Link":http://dl.dropbox.com/u/11379868/hideExample.zip)

Stripping down a problem to it's essential is a good way of discovering solutions, isn't it?
