Default size of window on different platforms

[guitargentlyweeps]

Hi,

I've searched the forum and tried different things to solve this to no avail.

I have an application that shows a QDialog derived dialog from a QMainWindow derived class. I'm building on a mac with a high res display and the dialog shows fine. When I build on a linux box with a lower resolution display, the top and bottom of the dialog extends above and below the screen respectively. If I use setFixedSize() on my dialog I can display the whole thing on this lower res display fine but then I can't re-size if I want to. Also, this is a ham handed way of sizing a window. Obviously using setMaximumHeight() or setMaximumWidth() won't work because they just restrict re-sizing. How can I use the dimensions of my display, which I can retrieve with a call to availableGeometry(), to size my dialog properly? What function can I plug these values into to achieve this? What am I missing here, this should be simple.

Thanks for the consideration in advance. Much appreciated.

Does it help if right after calling show() on your widget you call this line?

widget->resize(widget->sizeHint());

widget->resize(widget->sizeHint());

Thanks for your response. Unfortunately, this seems to have no effect.

One clue is that if instead of using widget->show(), I use widget->showMaximized(), the whole dialog will show and fill up the entire screen. The layouts in the dialog appear to be a little crowded, so maybe due to the size of the layouts in my dialog and the resolution of my display, it's not possible to fit properly? Hence, I can not get resize() to work right?

Sorry all. It looks like my problem all along was that my dialog with all of its layouts was just too big for the resolution of the monitor that I was attempting to display it on. I suppose that sizeHint() can only help so much. What I did was reorganized my layouts so that my dialog extended in a more horizontal fashion which helped.

Thanks to all who looked at this post. Much appreciated.
