Hello,
I was wondering, what is the preferred way to create a GUI with a
custom look-and-feel appearance, similar as e.g. QtCreator.
I have a modestly large application, using a QWidgets approach and I
use 'designer' to create the ui/layout.
The application has several modes/screens, which are accessible at the
moment through a tabview widget.
At the core of the application there is a QGLWidget, drawing lots of
data coming from the C++ core.
I would like to make the application appear a bit more modern, e.g.
with custom look-and-feel buttons/spin-boxes etc.
I recently discovered QML. Does it make sense to migrate to a QML
based approach? I'm thinking of creating the mainwindow together with
buttons to switch between the modes in QML. And instantiate my (c++
implemented) OpenGL widget in QML (and make it derive from QQuickItem).
Or should I stick with the QWidgets approach and use a stylesheet to
implement more 'fancy' looking things such as gradients and custom
look-and-feel components?
What does QtCreator use to implement the GUI? For example the
navigation bar at the left with the "Welcome", "Edit", "Design", etc.
buttons. I tried to look into the sources of QtCreator, but got a bit
lost.
There are multiple approaches possible. It depends a bit what you want
to achieve. I think QML is very promising, but the components are still
not very mature. That is only illustrated once more by yet another break
in there with QtQuickControls 2.0. Still, cool things are possible.
Showing OpenGL in QtQuick is certainly possible.
However, you can also consider a more conservative approach. If widgets
are serving you well and you just want a different look, you can also
implement your own style. I would recommend that over using style
sheets. Doing this will not give you fancy animations, but it will give
you all the widgets goodness and stability that
QML/Quick/Components/Controls/WhatEverItIsCalledToday so far is lacking.
