[Qt-creator] How to add custom property type to the designer?

[Jarvis]

Hello£¬I want to add custom property type to the designer.


I'm trying to do that£º



struct TestType { int x; int y; }; Q_DECLARE_METATYPE(TestType) class ... { Q_OBJECT Q_PROPERTY(TestType Test READ Test WRITE SetTest) ... };
But the property do not appear in the designer.Property type can only be Qt's own?(and Q_ENUM¡¢Q_FLAGS)

[Jaroslaw Kobus]

Yes, QDesigner supports only types it knows. However, the list of known types is quite large.


Taking into account that uic needs to convert an xml based property values into the C++ code, it wouldn't be easily possible without any plugin architecture / extension system of uic.

No, uic is not extensible.

OK£¬thanks. QT is there an example of uic extension(plugin)?
