Standard colors in QtCreator (KDE)

[A Former User]

Don't know how to do it from within a QML file but you can do it from C++:

#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QPalette>

int main(int argc, char *argv[])
{
    QGuiApplication app(argc, argv);

    QPalette systemPalette = QGuiApplication::palette();
    systemPalette.setColor(QPalette::Active, QPalette::Button, QColor("orange"));
    QGuiApplication::setPalette(systemPalette);

    QQmlApplicationEngine engine;
    engine.load(QUrl(QLatin1String("qrc:/main.qml")));

    return app.exec();
}

That code doesn't seem to change anything visually. Am I doing something wrong?

[A Former User]

It changes the system palette application wide, so the following will give you an orange rectangle:

    Rectangle {
        SystemPalette { id: systemPalette }
        anchors.fill: parent
        color: systemPalette.button
    }

I'm not sure we are discussing the same thing haha. I'd like for my Qt Application to fetch the systempalette of the OS, and apply that to my application.

@Rouleaux
I think there are some misunderstanding, it will be better if you post your code here so would be able to get that point on which this thread start and try to resolve too soon.

[A Former User]

@Rouleaux Oh, I think I misunderstood your intentions completely. So your actually want all your controls to look natively?

[Rouleaux]

@Vicky-Sharma Yes, sorry, that might clear things up.

import QtQuick 2.7
import QtQuick.Window 2.2
import QtQuick.Controls 2.0

Window {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")

    Button {
        id: button1
        x: 8
        y: 8
        text: qsTr("Nicotine Base")
    }
}

This is my QML. I'd like to know wether there is an option to provide the systemtheme (mine for example is BreezeDark), but then applicationwide. Now I have to apply SystemPalette to every single element, but I suppose there must be an easier way right?

Ok, so for natively looking widgets you'll need

• QT += widgets in your *.pro file
• QApplication in main.cpp (not QGuiApplication)
• QtQuick.Controls 1 (not 2)

E.g.:

main.cpp

#include <QApplication>
#include <QQmlApplicationEngine>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QQmlApplicationEngine engine(QUrl(QLatin1String("qrc:/main.qml")));
    return app.exec();
}

main.qml

import QtQuick 2.7
import QtQuick.Controls 1.4

ApplicationWindow {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")

    Button {
        text: "Exit"
        anchors.centerIn: parent
        onClicked: Qt.quit()
    }
}

@Wieland Shoot, I've just started using QtQuick.Controls 2.0..

[Vicky Sharma]

@Rouleaux
unfortunately i don't have 5.7 but i checked on 5.6 and rewrite few thing, you may check too as well as "Wieland" is also post write one check and revert if any error.
import QtQuick 2.5
import QtQuick.Window 2.2
import QtQuick.Controls 1.4

Window {
visible: true
width: 640
height: 480
title: qsTr("Hello World")

Button {
    id: button1
    x: 8
    y: 8
    text: qsTr("Nicotine Base")
}

}

@Rouleaux I thought you were only complaining about the white button text, because, yes, it actually shouldn't use the system palette at all, unless you add support for native widgets as described above. sry! =)

@Rouleaux said:

No native widgets with Controls 2. You need to supply a custom style then (see your other thread).

[Rouleaux]

@Wieland I understand now. Thank you very much for your help!
