[Solved] Create a dialog box with QDesigner

  • Regards

    I am working with QDesigner to create a simple dialog box, as yet not allocate space to create the effect you want.

    I want to create a dialog box divided into two parts, where the first occupy at least two thirds of the area of the dialog box and the second the remaining space (at most one-third).

    In each of the two areas I want to put a QGroupBox empty, alone with his title.

    I've been testing with QHBoxLayout, QVBoxLayout and QGridLayout, but I can not do exactly what I want, the space of the dialog box always halved.

    My thanks in advance to who can give me some advice or suggestion.

  • Hello!

    Have you tried with a QSpacer? You can fix its length and position. A layout will always divide into equal parts the available amount of space. Once the spacer is introduced, then you could be able to use the layouts.


  • Thanks for the advice, but I do not understand exactly what you suggest.

    Are you suggesting that I use a QSpacer within QLayout or am I misunderstanding?

  • In the designer under the smart/tools panel on the left you will find Horizontal/Vertical spacers, you can place them in your dialog as per your requirement.

    The solution without additional elements would be to create QVBoxLayout and add those two QGroupBoxes there.
    Then, in the sizePolicy property group set vertical stretch to 2 in the first groupbox and to 1 in the second.

  • Like above, you a layout (doesn't really matter if a Hbox or Grid is used) and set the stretch factor and the sizeHint should have a 1 to 2 factor to get it started at the proper size! Should work nice then

  • I have successfully managed to create dialog box with space divided any way you want (actually I did several days ago, specifically January 13, 2013 ... I had forgotten to thank all of you).

    As I said, thank you all for your comments and help.
