QCustomWindow

QCustomWindow (former QCustomTitlebar) is a project in which its main class (QCustomWindow) inherits its properties from QWidget, wrapping a QMainWindow class instance.

It basically consists of a customized widget providing a customized non-client area which wraps a QMainWindow, as represented in the following image:

Support and Documentation

Docs elaboration is still in progress :( ...
Should you have any doubts, do not hesitate in contacting me through my email.

Features:

• Dynamic pointer styles;
• Compatible with Qt5 and Qt6;
• Customized stylesheet (light theme);
• Uses new QWindow's move/resize API by default (use QCustomWindow::setForceCustomMove(bool) and QCustomWindow::setForceCustomResize(bool) so as to change behaviour);
• Window title update (QWidget::setWindowTitle(QString)) working properly;
• Better performance (when compared to previous versions);
• Direct access to QMainWindow instance (without restricted access to its methods and properties);
• Dynamically Linked Library (DLL) binaries available for Windows.

Observations:

• Should you use a QStatusBar, it is strongly recommended that you provide at least a basic stylesheet which removes its borders as well;
• Limitations from release v2.x are no longer an actual issue.

Distribution (available versions):

• DLL + LIB + headers;
• Stactic linking/source files;
• Qt Creator/Designer plugin.

CustomTitlebar open source code

• You can download and make modifications in the source code, accordingly to Mozilla Public Licence v2.0 terms;
• The licence is available in the root of the project directory and must be always shipped with it.
