Main Window frame height

[^NyAw^]

Hi,

Is there anyway to get the height of the frame of the window(frame where there is the close button,...)?

Thanks,

Yes, you can:

int height = window->style()->pixelMetric(QStyle::PM_TitleBarHeight);

int height = window->style()->pixelMetric(QStyle::PM_TitleBarHeight);

To copy to clipboard, switch view to plain text mode 

but may I ask what do you intend to do with it?

Hi,

My application has toolbars, menus and docks, and I want that the central widget use all the avaiable space. So I take the application height less toolbars,menus,docks and upper frame.

Thanks,

Hmm.. You shouldnt have to do that. Qt will handle the sizing for you. How are you setting up your UI?

Could you tell me how? I reimplemented the method "resizeEvent" to resize the centralWidget to the maximum width and height. Note that if Docks are resized, the centralWidget will be resized too.

My UI is a centralWidget (the main window was done with Designer) and it has a QGridLayout that manages some windows (like OpenGL windows). So, depending on the size of the main Window and the size of the Docks, toolBars, ..., the size of the internal widget have to be resized.

Hmm? But QMainWindow does that automatically (of course, provided that all the central widget, docks etc. are properly added via suitable methods in QMainWindow API). Size policies, stretch factors and such are there if you need to adjust resizing.

Hi,

So, I have to adjust the Size policies to get it automatically be done. I am right? I will read abou it. I supose that my problem is that I always try to do it myself without thinking that maybe it is done yet(maybe I have to read a little more, but sometimes I really don't know where to find the information, Qt is great but it has a lot of classes and sometimes I don't know where to find what I want).

Well, it's hard to say exactly what do you need. But you rarely need to manage any geometries by hand. Perhaps you could provide a screenshot and then explain how do you want all the child windows to behave?

Hi,

Well, the only that I need is that the centralWidget of the mainWindow occupies all tha avaiable space.

I had inserted a QSrollArea instead of the centralWidget because time ago I did'n need this behavior and the scrollBars were a good solution. Now I don't want to use scrollArea, and I want to use the maximum centralWidget size avaiable.

Did you apply a top level layout? Unselect child widgets, open up context menu over the background of the form and select a layout. See this thread for a screenshot: http://www.qtcentre.org/forum/f-qt-d...lved-9897.html

Sorry, I didn't said that I have a QGridLayout (all the code is handwritten). And I don't do it with Designer because the number of columns and rows of windows(like OpenGL widgets) can be modified.

Thanks for replies, but it works using

int height = window->style()->pixelMetric(QStyle::PM_TitleBarHeight);

int height = window->style()->pixelMetric(QStyle::PM_TitleBarHeight);

To copy to clipboard, switch view to plain text mode 

as you told me.

Next time I will try to try using size policies.

Thanks,
