    Default Re: Issue when i open window from mainwindow after the 1st time - it will open very s

    In my code code attached i have this issues:
    1 - when i open the edit window at 1st time the window will be open right, next time it will open very small?
    (if i make some mistake in my code tell me what is the right procedure to do the job by explain me with some code, thank you)
    2 - I'm trying to reduce the "color-label" to the width of the combobox, i have tried some but with no effect, how i can do it?
    3 - when i try to close the main window by pressing with the mouse on X button, no happen?

    Qt compiler is showed this message after the 1st open:
    QWidget::setLayout: Attempting to set QLayout "" on EditObject "", which already has a layout


    Added after 38 minutes:


    after i used an auxiliary update_val:
    Qt Code:
    1. void EditObject::window_elements_update()
    2. {
    3. ....
    4. if (update_val){
    5. update_val = 0;
    6. setLayout(final_layout);
    7.  
    8. }
    9. else {
    10. layout()->update();
    11. }
    12. }
    To copy to clipboard, switch view to plain text mode 
    and the message "QWidget::setLayout: Attempting to set QLayout "" on EditObject "", which already has a layout" disappeared but the window still small after the 1st open window
