Member Function Documentation

virtual void AboutWindow::DrawWidget ( const Rect r,
int  widget 
) const [inline, virtual]

Draw the contents of a nested widget.

Parameters:
r Rectangle occupied by the widget.
widget Number of the widget to draw.
Note:
This method may not change any state, it may only use drawing functions.

Reimplemented from Window.

Definition at line 454 of file misc_gui.cpp.

virtual void AboutWindow::OnPaint (  )  [inline, virtual]

The window must be repainted.

Note:
This method should not change any state, it should only use drawing functions.

Reimplemented from Window.

Definition at line 449 of file misc_gui.cpp.

References Window::DrawWidgets().

virtual void AboutWindow::SetStringParameters ( int  widget  )  const [inline, virtual]

Initialize string parameters for a widget.

Calls to this function are made during initialization to measure the size (that is as part of InitNested()), during drawing, and while re-initializing the window. Only for widgets that render text initializing is requested.

Parameters:
widget Widget number.

Reimplemented from Window.

virtual void AboutWindow::UpdateWidgetSize ( int  widget,
Dimension size,
const Dimension padding,
Dimension fill,
Dimension resize 
) [inline, virtual]

Update size and resize step of a widget in the window.

After retrieval of the minimal size and the resize-steps of a widget, this function is called to allow further refinement, typically by computing the real maximal size of the content. Afterwards, size is taken to be the minimal size of the widget and resize is taken to contain the resize steps. For the convenience of the callee, padding contains the amount of padding between the content and the edge of the widget. This should be added to the returned size.

Parameters:
widget Widget number.
size Size of the widget.
padding Recommended amount of space between the widget content and the widget edge.
fill Fill step of the widget.
resize Resize step of the widget.

Reimplemented from Window.
