    In your constructor you use :

    @    if (showdckWidgetChkBox->isChecked()) {
            showdckWidgetChkBox->show();
        } else {
            showdckWidgetChkBox->hide();
        }@

    This means that only once the hide or show will work.

    On the same place you should use a connect :
    Use the checkbox as sender and the dockwidget uses a slot to act on that.

      example code
      @connect(ui->checkBox, SIGNAL(toggled(bool)), ui->dockWidget, SLOT(setHidden(bool)));@

      of course you should adapt the widget names to your needs.

            Heh, awesome, thanks for the help, that worked, sorry, I should have known this, as much as I've been studying Qt, you'd think, by now, after 3 or more months, I know it all, hahaha.. Honestly, I don't, it's due to my laziness and not doing anything other than Menus and QTextEdits, decided to try something different for a change, and so far, heck yeah, =). Thanks again.

                Looks to me like almost all things in Qt requires Sigs/Slots..

                    Heh, have to write more codes it appears, when a user clicks the X, the Checkbox doesn't automatically Uncheck. Also, having an issue with getting the DockWidget to stay small, I did get it so it stays at bottom, but now it's onto learning how to make it resize, tried the dckwidget->setGeometry(0, 150, 1024, 100); but it didn't appear to do anything, =/. It still stays just as large as the parent window.

                      You need to emit a signal from the dockwidget and connect it with a slot of the checkbox.

                          It's not that difficult.
                          Hint : Use the same approach as before. Look for a signal and slot with a bool argument.
