Still need help: Best way to have application "skins"?

[jpn]

Thanks! Only one question. Later in my code, the "core" of it, how would I refer to the objects on my forms, if they have the same names? Do I have to use plainUi.myTextBoxObject, or can I just ise myTextObject like in multi-inheritance? Thanks again!

That's a good point I didn't think of. Unfortunately those two ui members have nothing in common... How about introducing additional pointers to required objects (hopefully you don't have tons of them) so that you don't have to continuously check the mode and clutter your code with conditional blocks?

class MyFancyWidget
{
    ...
private:
    Ui::FancyWidget fancyUi;
    Ui::PlainWidget plainUi;
 
    QTextEdit* myTextObject;
    ...
};
 
void MyFancyWidget::setFancyMode()
{
    ...
    myTextObject = fancyUi.myTextObject;
}
 
void MyFancyWidget::setPlainMode()
{
    ...
    myTextObject = plainUi.myTextObject;
}

class MyFancyWidget
{
    ...
private:
    Ui::FancyWidget fancyUi;
    Ui::PlainWidget plainUi;

    QTextEdit* myTextObject;
    ...
};

void MyFancyWidget::setFancyMode()
{
    ...
    myTextObject = fancyUi.myTextObject;
}

void MyFancyWidget::setPlainMode()
{
    ...
    myTextObject = plainUi.myTextObject;
}

To copy to clipboard, switch view to plain text mode

Great!! Thanks! It would take me several years to think of that one!

Any chance I could create some for(int i=0; i<childWidgets().length(); i++) loop? Note that childWidgets() may not be an actual property, but for the sake of this question...

So could I somehow apend that name? If it's not possible, it's ok.

I don't need to do much, just a couple of buttons and a text box.

Also, where would I put the connect()'s? In each of the plainUi and fancyUi functions, or in the constructor?

Thanks a lot!

Do you mean something like:

QPushButton* button = findChild<QPushButton*>("myButtonWithCertainObjectName");
if (button) // just to assure it was found
   button->doSomething();
 
// or
 
QList<QPushButton*> allButtons = findChildren<QPushButton*>();
foreach (QPushButton* button, allButtons)
   button->doSomething();

QPushButton* button = findChild<QPushButton*>("myButtonWithCertainObjectName");
if (button) // just to assure it was found
   button->doSomething();

// or

QList<QPushButton*> allButtons = findChildren<QPushButton*>();
foreach (QPushButton* button, allButtons)
   button->doSomething();

The whole GUI, including all widgets, gets re-created when you call respective setupUi(). So you must re-establish all signal-slot connections every time the "mode" is changed.
