omit path builders in Python to locate those files.Making use of this internal resource store is of advantage to: That file has a XML structure and is used to register binary files, like PNG images, with Qt in-app. Qt has the concept of an in-app resource store, which is defined in resources.qrc files on a plugin level. Size policies define the widget's size behavior within the layout.ĭeprecation Notice: the concept of a resource store is actually not very useful for Python based apps, so the next version of PyQt will not support pyrcc anymore and instead you'll rely on more common Python patterns to import files. When the user changes the window size, it can be disorienting if a button scales with the resizing. Size policies are important! When building bigger GUIs it will be increasingly important to define how widgets behave visually within their layout.

It will help a lot when you access them in the code later on, which becomes more important with a multitude of widgets. Try out different layout types and add a few widgets to see the behavior.Įvery widget needs a unique name property defined in QObject.objectName! It will auto-name your widgets and while it's not required it's highly recommended to use structured naming for widgets. well, layouting (to keep consistent element spacing when resizing etc.). Important Qt Designer conceptsĮvery container widget needs a layout!. Quick access to different layouts for container widgets, see its importance right below.
and finally QDialogButtonBox, which has mostly functional properties, e.g. QWidget, which exposes multiple properties, mostly layout related. QObject, which only exposes the objectName property and will be widget identifier in your code. the QDialogButtonBox is sub-classed from (in descending order): you can immediately see the inheritance tree for each widget by examining the tabs of the Property dialog. QDialogButtonBox for the OK/Cancel button group It gives you a whole lot more information though: So it's also a good reference to available widget properties to be modified. You didn't see any actual code yet, but these properties are accessible methods through the Python class of your GUI. 3 Property EditorĮach widget exposes a list of properties, like geometry or font, which you will find in this panel. when they are overlapping each other in the dialog. But sometimes it's good to see the hierarchy of widgets or select it from a list, e.g. You can click on widgets in your dialog to select them. There's also several custom QGIS widgets at the very bottom, which extend functionality of Qt widgets (like CRS picker). Drag a few widgets into your dialog and experiment a bit. In Qt, all GUI elements are classified as Widgets, which can have all kinds of actual UI functionality like buttons, containers or user input elements. For easier navigation, here's a quick breakdown of the Qt Designer interface: In the startup dialog, create a new Dialog with Buttons Bottom dialog, which will give you a bare-bone UI. It's the easiest way to create and alter UI files for QGIS plugins. Luckily, QGIS ships the program with its core on all operating systems and should be available as an executable on your computer. Qt Designer is an easy-to-use program to build UI's for Qt frameworks. QGIS 3 Plugins - Set up Plugin Repository. QGIS 3 Plugins - Geocoding with Nominatim Part 4 (Tests & CI).
