Expand description
Bindings for QtGui library.
This crate was generated using cpp_to_rust.
This is work in progress, so the API will significantly change in the future. Some methods are missing, and some are inconvenient to use. Some methods are unsafe even though they are not marked as unsafe. Users must carefully track ownership of the objects, as usual Rust guarantees do not take effect. This will hopefully improve in the future. Please report any issues to the issue tracker.
This crate was generated for Qt 5.8.0. If Qt compatibility guarantees take effect, it should be compatible with future minor releases and with past and future patch releases, but API added in future releases won’t be available. The crate is not compatible with past minor Qt releases. If you need to use a Qt version incompatible with this crate, use qt_generator to generate crates for your Qt version.
Refer to qt_core crate documentation for general information about Qt crates.
Note that if you use qt_widgets, you should use qt_widgets::application::Application
as the application object, and if you use qt_gui but not qt_widgets, you should use
qt_gui::gui_application::GuiApplication.
