Member Function Documentation

◆ abortEditing()

void OpenOrienteering::DrawTextTool::abortEditing ( )

protected

◆ clickPress()

void OpenOrienteering::DrawTextTool::clickPress ( )

overrideprotectedvirtual

Called when the left mouse button is pressed.

Reimplemented from OpenOrienteering::MapEditorToolBase.

◆ clickRelease()

void OpenOrienteering::DrawTextTool::clickRelease ( )

overrideprotectedvirtual

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

Reimplemented from OpenOrienteering::MapEditorToolBase.

◆ dragFinish()

void OpenOrienteering::DrawTextTool::dragFinish ( )

overrideprotectedvirtual

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::DrawTextTool::dragMove ( )

overrideprotectedvirtual

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

Reimplemented from OpenOrienteering::MapEditorToolBase.

◆ drawImpl()

void OpenOrienteering::DrawTextTool::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.

◆ finishEditing()

void OpenOrienteering::DrawTextTool::finishEditing ( )

overrideprotectedvirtual

Finishes editing if it is currently in progress.

Deriving functions shall call this class' implementation (which calls setEditingInProgress(false)).

Reimplemented from OpenOrienteering::MapEditorTool.

◆ initImpl()

void OpenOrienteering::DrawTextTool::initImpl ( )

overrideprotectedvirtual

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

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.

◆ updatePreview()
