virtual void TownViewWindow::OnInvalidateData ( int  data = 0,
bool  gui_scope = true 
) [inline, virtual]

Some data on this window has become invalid.

Parameters:
data Information about the changed data.
gui_scope Whether the call is done from GUI scope. You may not do everything when not in GUI scope. See InvalidateWindowData() for details.

virtual void TownViewWindow::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 TownViewWindow::OnResize (  )  [inline, virtual]

Called after the window got resized.

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

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

virtual void TownViewWindow::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 TownViewWindow::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.
