## Member Function Documentation

virtual void VehicleListWindow::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.

virtual void VehicleListWindow::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.

virtual void VehicleListWindow::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.

virtual void VehicleListWindow::OnPaint | ( |  | ) | `[inline, virtual]`

The window must be repainted.
