    Default 2x2 Grid Layout with custom widgets and widgets show/hide problem

    Hi guys!
    I have faced the following problem while programming in QT 4.7:
    I have a main window layed out horisontally, containing kind of a control panel (left) and QGridLayout(right). QGridLayout is 2x2 and contains 4 custom widgets derived from QWidget class. When a particular widget in a grid is doubleclicked it is maximized. I have accomplished it by setting the visibility of the rest of widgets in a grid to false. When such a maximized widget is doubleclicked again, the view should revert to it's normal state (2x2).

    And the problem is: when i am setting the wisibility of all 4 widgets within the gridlayout to true, I can see the process of grid resizing (5 steps) instead of seeing the whole grid recalled at once. Such behaviour is non-pleaseant and annoying. Is there a way to block the grid visibility before all elements are recalculated? I have tried several approaches found on the net but none of them worked for me.

    Best regards.

    //*problem solved
    My custom widget used the repaint() method within showEvent(). The repaint() was substituted with update() as the documentation says and the probelm disappeared. Now all widgets appear at once =). thx dr.greenthumb, you're da s*t
