Get the advanced color picker only, from QColorDialog

  • pickerShot.png Is it possible to load advanced picker from QColorDialog into a widget? By advanced picker I mean like the one in the picture.
    I made a color picker with colors of my choice but still want to let the user define their own colors and add it to a custom colors list. I could write something like the one in the picture myself but was thinking if it possible to just get the thing from QColorDialog and add it into a layout/widget.

    Well the
    class QColorPicker : public QFrame

    is only defined in .cpp it seems its not possible to reuse.

    But we can steal one from a QColroDialog and insert into a layout

    But im not use if we can connect to it and use it really.

    btw i steal it like this

        QColorDialog d;    
        d.dumpObjectTree(); // to see the class names inside..
        auto list = d.findChildren<QWidget *>();
        for (QWidget *w : list) {
            if (strcmp( w->metaObject()->className(), "QColorPicker")  == 0)
                    ui->test->addWidget(w); // test is a layout

  • @mrjj I tried implementing this in PySide2. This method was just not going well with my full code for some reason. Ended up writing a whole new class and made my own advanced color picker (not complete) it gives me more control too. But this is a nice method and can actually be used in certain cases. Thank you for your effort.

    Well since we can't use the type QColorPicker, it was not really possible to connect to its signals
    so it was not very useful anyway.
    So a custom color picker sounds much better.
    If it turns out good, maybe share it with the world ?

  • @mrjj Yes I will. It's part of a bigger project, which includes the color picker, event calender etc. I will be sharing it with a GPL licence.
