Editing User interface files

Editing User interface files

Editing User interface files is done through .ui files.

By default in a new app you have the mainform.ui which can be viewed and edited in its dedicated visual editor:

Figure 47: The user interface file editor

Here you will place the widgets that can be found in the toolboxes and organize them in layouts in order to get good behavior when resizing your app later.

The user interface editor consists of several parts which are presented in the following sections.
