自动调整qt应用程序的大小。 （主窗口）

Question

I've recently started development in qt and so far it's going good. Now my question is : can I auto re-size qt application as per my screen resolution ? Say, I 've a main window designed for 1366 x 768. And it works for one system. While porting it to another system which supports 1280 x 800 or 800 x 600, is there an easy way to do it ? without changing UI design in creator ?

I appreciate any help regarding this.

Thanks in advance.

Answer 1

Try do this (for example put it in the mainWindow's constructor)

this->showMaximized();

Anyways you can simply get resolution of current screen with this code:

qDebug() << QApplication::desktop()->size();

And QWidget have resize() method. QMainWindow inherits QWidget , so you can use resize() in your mainWindow.

Qt (and many other UI toolkit) solve auto resize problem with a layout manager, it depend on how do you design your UI to choose a layout or mix them. See http://qt-project.org/doc/qt-4.8/layout.html
