Stylesheets and QML - widget application being changed to QML, what is the best way to reuse stylesheets?

? Offline

This is the test app I have been playing with (full app far to big for this site) - will give you a menu "Item 1", "Item 2" etc (even though there is a colour value it is not used).

main.cpp
@
#include <QtGui/QGuiApplication>
#include "qtquick2applicationviewer.h"
#include <QQmlContext>
//#include <QDeclarativeContext>
#include "menu.h"

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

QtQuick2ApplicationViewer  viewer;

CMenu menu(&viewer);

viewer.rootContext()->setContextProperty("myMenu", &menu);

//QtQuick2ApplicationViewer viewer;
viewer.setMainQmlFile&#40;QStringLiteral("qml/GuideNext/main.qml"&#41;);

QList<QObject*> dataList;
   dataList.append(new DataObject("Item 1", "red"));
   dataList.append(new DataObject("Item 2", "green"));
   dataList.append(new DataObject("Item 3", "blue"));
   dataList.append(new DataObject("Item 4", "yellow"));

viewer.rootContext()->setContextProperty("myModel", QVariant::fromValue(dataList));
viewer.showExpanded();

return app.exec();

}

Dolphin - thank you! I will study this code in near future :)

So, if my option is to style in the QML what is my best bet for custom styling? The app is very simple but needs to allow the user to change colour/font/font style/font size and retain those settings. With widgets I was starting with a stylesheet and updating it with a custom block of css added to the bottom of the file so there was no need to write code to create a new file just have the existing one but let the code at the bottom overwrite what came before. So if the stylesheet said background should be white but user wanted it to be blue 'original stylesheet+set background to blue' would be loaded.

The 'zoom' setting also needs to be retained PER SCREEN. It is such a simple application for non technical elderly/visually impaired users that 'zoom' is really just the font size but they need to have the 'zoom' setting per screen - again, in the widget version it was just reloading the stylesheet and applying an font size change each time a new screen was display so minimal data to retain.

PS I am using the word screen to cover the case of a menu change (which is really someone clicking on a Listview causing the data on the Listview to be updated (click on "Letters and documents" and the Lisview is updated to give options "Write a letter", "Find a document" etc) but at the same time the 'zoom' setting is updated for that 'menu page' (i.e. set of Listview data)...... and also the case that the user has gone into a new application (they might want email to be big and letter writing to be small based on the layout of the screen or whatever other preference might apply to them).

[quote author="Jens" date="1358864467"] But In 5.1 it should be a bit simpler to create custom styled sliders, buttons etc.[/quote]

Are there any examples of this in the Qt 5.1.0 rc?

Jens

The docs are available here:
http://doc-snapshot.qt-project.org/qt5-stable/qtquickcontrolsstyles/qtquickcontrolsstyles-index.html

There are also some styling examples in both the gallery and touch example that ships with 5.1 RC, and expect more examples or guides in the future.

I am glad that lots of informative stuff is shared here! I am a beginner and in web development and I have some doubts regarding them! Can you suggest the best ways to change the visual layouts? In addition please tell me how style sheets operation change in two mark ups?
