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

The window must be repainted.

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

virtual void IndustryViewWindow::OnQueryTextFinished | ( | char * | str | ) | `[inline, virtual]`

The query window opened from this window has closed.

Parameters:

  | str | the new value of the string, NULL if the window was cancelled or an empty string when the default button was pressed, i.e. StrEmpty(str).

virtual void IndustryViewWindow::OnResize | ( |  | ) | `[inline, virtual]`

Called after the window got resized.

For nested windows with a viewport, call NWidgetViewport::UpdateViewportCoordinates.

Reimplemented from Window.

Definition at line 761 of file industry_gui.cpp.

References NWidgetViewport::UpdateViewportCoordinates(), and Window::viewport.

virtual void IndustryViewWindow::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.

Definition at line 691 of file industry_gui.cpp.

References SetDParam(), and Window::window_number.

virtual void IndustryViewWindow::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.
