Member Function Documentation

void PlaneOverviewCameraTool::Activate (   )  [virtual]

Switch on a tool. Inherited classes also register events they want to respond to with the PreviewToolHelper. As events are lost when the tool is deactivated without notification to the PreviewTool, things from the last activation can be cleaned up here too. Implements Tool. Definition at line 120 of file OverviewCameraTool.cpp. References down, and ToolHelper::NotifyMe().

void PlaneOverviewCameraTool::ChangeZoomLevel (  bool  zoomIn, double  scale = 1.1 )

Definition at line 192 of file OverviewCameraTool.cpp. References VisualizationState::ForceRequireRedraw(), PlaneOverviewVisualizationState::getR(), ToolHelper::GetVisualizationStatePtr(), VisualizationState::Redraw(), VisualizationState::SetDirtyViewport(), and PlaneOverviewVisualizationState::setR(). Referenced by KeypressEvent(), and MouseWheelEvent().

void PlaneOverviewCameraTool::KeypressEvent (  int  keycode, int  modifiers, bool  pressed )  [virtual]

Notify of a Keypress event. Currently unused as the preview cannot get keyboard input focus. Reimplemented from Tool. Definition at line 211 of file OverviewCameraTool.cpp. References ChangeZoomLevel().

void PlaneOverviewCameraTool::MouseButtonEvent (  wxMouseEvent &  e  )  [virtual]

Notify of a mouse button press on the panorama preview. Parameters: e  The event created by wxWidgets. Reimplemented from Tool. Definition at line 173 of file OverviewCameraTool.cpp. References down, PlaneOverviewToolHelper::getPlaneX(), PlaneOverviewToolHelper::getPlaneY(), ToolHelper::GetVisualizationStatePtr(), PlaneOverviewVisualizationState::getX(), PlaneOverviewVisualizationState::getY(), start_pos_x, start_pos_y, start_x, and start_y.

void PlaneOverviewCameraTool::MouseMoveEvent (  double  x, double  y, wxMouseEvent &  e )  [virtual]

Notify when the mouse pointer has moved over the panorama preview. The coordinates are in the space of the panorama output at full size, with no output cropping. Parameters: x  The horizontal position of the mouse pointer in panorama pixels. y  The vertical position of the mouse pointer in panorama pixels. e  The event created by wxWidgets. Reimplemented from Tool. Definition at line 128 of file OverviewCameraTool.cpp. References DEG_TO_RAD, VisualizationState::ForceRequireRedraw(), PlaneOverviewVisualizationState::getFOV(), PlaneOverviewVisualizationState::getR(), VisualizationState::GetViewer(), ToolHelper::GetVisualizationStatePtr(), VisualizationState::Redraw(), PlaneOverviewVisualizationState::setX(), PlaneOverviewVisualizationState::setY(), start_pos_x, start_pos_y, start_x, and start_y.

void PlaneOverviewCameraTool::MouseWheelEvent (  wxMouseEvent &  e  )  [virtual]

Notify of a mouse wheel event on the panorama preview. Parameters: e  The event created by wxWidgets. Reimplemented from Tool. Definition at line 204 of file OverviewCameraTool.cpp. References ChangeZoomLevel().
