Member Function Documentation

clickPress()

void OpenOrienteering::EditLineTool::clickPress ( )

overridevirtual

Called when the left mouse button is pressed.

Todo:

Provide a PathObject::convertToStraight(hover_line) ?

Todo:

Provide a PathObject::convertToCurve(hover_line) ?

Reimplemented from OpenOrienteering::MapEditorToolBase.

clickRelease()

void OpenOrienteering::EditLineTool::clickRelease ( )

overridevirtual

Called when the left mouse button is released without a drag operation before.

Reimplemented from OpenOrienteering::MapEditorToolBase.

deleteHighlightObject()

void OpenOrienteering::EditLineTool::deleteHighlightObject ( )

protected

Deletes the highlight object if it exists and correctly removes its renderables.

dragCanceled()

void OpenOrienteering::EditLineTool::dragCanceled ( )

overridevirtual

Reimplemented from OpenOrienteering::MapEditorToolBase.

dragFinish()

void OpenOrienteering::EditLineTool::dragFinish ( )

overridevirtual

Called when a drag operation is finished.

There is no need to update the edit operation with the current cursor coordinates in this call as it is ensured that dragMove() is called before.

Reimplemented from OpenOrienteering::MapEditorToolBase.

dragMove()

void OpenOrienteering::EditLineTool::dragMove ( )

overridevirtual

Called when the mouse is moved with the left mouse button being pressed.

Reimplemented from OpenOrienteering::MapEditorToolBase.

dragStart()

void OpenOrienteering::EditLineTool::dragStart ( )

overridevirtual

Called when a drag operation is started.

This happens when dragging the mouse some pixels away from the mouse press position. The distance is determined by start_drag_distance. dragMove() is called immediately after this call to account for the already moved distance.

Reimplemented from OpenOrienteering::MapEditorToolBase.

drawImpl()

void OpenOrienteering::EditLineTool::drawImpl ( QPainter *  painter, MapWidget *  widget  )

overrideprotectedvirtual

Must draw the tool's graphics.

The implementation draws the preview renderables. MapEditorToolBase::draw() draws the activated tool helpers afterwards. If this is not desired, you can override draw() directly.

Reimplemented from OpenOrienteering::MapEditorToolBase.

hoveringOverFrame()

bool OpenOrienteering::EditLineTool::hoveringOverFrame ( ) const

inlineprotected

initImpl()

void OpenOrienteering::EditLineTool::initImpl ( )

overrideprotectedvirtual

Can do additional initializations at a time where no other tool is active (in contrast to the constructor)

Reimplemented from OpenOrienteering::MapEditorToolBase.

keyPress()

bool OpenOrienteering::EditLineTool::keyPress ( QKeyEvent *  event )

overrideprotectedvirtual

Called when a key is pressed down. Return true if the key was processed by the tool.

Reimplemented from OpenOrienteering::MapEditorToolBase.

keyRelease()

bool OpenOrienteering::EditLineTool::keyRelease ( QKeyEvent *  event )

overrideprotectedvirtual

Called when a key is released. Return true if the key was processed by the tool.

Reimplemented from OpenOrienteering::MapEditorToolBase.

mouseMove()

void OpenOrienteering::EditLineTool::mouseMove ( )

overridevirtual

Called when the mouse is moved without the left mouse button being pressed.

Reimplemented from OpenOrienteering::MapEditorToolBase.

mouseMoveEvent()

bool OpenOrienteering::EditLineTool::mouseMoveEvent ( QMouseEvent *  event, const MapCoordF &  map_coord, MapWidget *  widget  )

overridevirtual

Reimplemented from OpenOrienteering::MapEditorTool.

mousePressEvent()

bool OpenOrienteering::EditLineTool::mousePressEvent ( QMouseEvent *  event, const MapCoordF &  map_coord, MapWidget *  widget  )

overridevirtual

Reimplemented from OpenOrienteering::MapEditorTool.

mouseReleaseEvent()

bool OpenOrienteering::EditLineTool::mouseReleaseEvent ( QMouseEvent *  event, const MapCoordF &  map_coord, MapWidget *  widget  )

overridevirtual

Reimplemented from OpenOrienteering::MapEditorTool.

objectSelectionChangedImpl()

void OpenOrienteering::EditLineTool::objectSelectionChangedImpl ( )

overrideprotectedvirtual

Called when the object selection in the map is changed.

This can happen for example as result of an undo/redo operation.

Implements OpenOrienteering::MapEditorToolBase.

updateDirtyRectImpl()

int OpenOrienteering::EditLineTool::updateDirtyRectImpl ( QRectF &  rect )

overrideprotectedvirtual

Must include the area of all custom drawings into the rect, which already contains the area of the selection preview and activated tool helpers when this method is called.

Must return the size of the pixel border, or -1 to clear the drawing.

Reimplemented from OpenOrienteering::MapEditorToolBase.

updateHoverState()

void OpenOrienteering::EditLineTool::updateHoverState ( const MapCoordF &  cursor_pos )

protected

Recalculates hover_line.

updatePreviewObjects()

void OpenOrienteering::EditLineTool::updatePreviewObjects ( )

overrideprotectedvirtual

In addition to the base class implementation, updates the status text.

Reimplemented from OpenOrienteering::MapEditorToolBase.

updateStatusText()

void OpenOrienteering::EditLineTool::updateStatusText ( )

overrideprotectedvirtual

Must update the status bar text.

Implements OpenOrienteering::MapEditorToolBase.
