Detailed Description

This class is a superclass for all mode handlers. By default, all events are ignored.

Member Function Documentation

virtual void CanvasMode::activate ( bool  fromGesture)
inlinevirtual

Is called when this mode becomes active, either because it was selected by the user (fromgesture == false) or because a gesture completed and the canvas returns back to this mode (fromGesture == true)

Reimplemented in LineMove, RulerGesture, RectSelect, ResizeGesture, CanvasMode_EditArc, CanvasMode_EditMeshPatch, CanvasMode_EditPolygon, CanvasMode_EditSpiral, CanvasMode_EditWeldPoint, CanvasMode_EditMeshGradient, CanvasMode_FrameLinks, CanvasMode_Normal, CanvasMode_ObjImport, CanvasMode_Edit, CanvasMode_Magnifier, CanvasMode_Rotate, CreateMode, CanvasMode_EditGradient, MeasurementsMode, CanvasMode_Panning, CanvasMode_EditTable, BezierMode, CalligraphicMode, FreehandMode, CanvasMode_ImageImport, CellSelect, TableResize, CanvasMode_CopyProperties, CanvasMode_EyeDropper, ColumnResize, RowResize, CanvasMode_NodeEdit, and PanGesture.

void CanvasMode::commonkeyPressEvent_NormalNodeEdit ( QKeyEvent *  e)
protected

If we have a doc and we are not changing the page or zoom level in the status bar

With no item selected we can:

  • With space, get into panning mode (modePanning)
  • With PageUp, scroll up
  • With PageDown, scroll down

  • With Tab, change active document windowActivated

    Now if we have an item selected

  • In normal mode we can: – Use backspace or delete to delete the item – Use itemRaise action shortcut to raise an item (actionmanager.cpp connect, no code here) – Use itemLower action shortcut to lower an item (actionmanager.cpp connect, no code here) – Use the arrow keys to move an item or group around for !inches: With no meta, by 1.0 unit Ctrl, by 10.0 units Shift by 0.1 units Ctrl Shift 0.01 units
    • For inches: With no meta, by 1.0 pt Ctrl, by 1.0 unit Shift by 0.1 units Ctrl Shift 0.01 units – Use the arrow keys to resize an item: Alt right arrow, move right side outwards (expand) Alt left arrow, move left side outwards (expand) Alt Shift right arrow, move left side inwards (shrink) Alt Shift left arrow, move right side inwards (shrink) – In edit mode of an image frame, use the arrow keys to resize the image: (flows to pageitem_imageframe for control) Alt right arrow, move right side of image outwards (expand) Alt left arrow, move right side inwards (shrink) Alt down arrow, move bottom side downwards (expand) Alt up arrow, move top side inwards (shrink)
virtual void CanvasMode::deactivate ( bool  forGesture)
inlinevirtual

Is called when this mode becomes inactive, either because the canvas switches to another mode (forGesture == false) or because a gesture is activated (forGesture == true)

Reimplemented in LineMove, RulerGesture, RectSelect, ResizeGesture, CanvasMode_EditArc, CanvasMode_EditMeshPatch, CanvasMode_EditPolygon, CanvasMode_EditSpiral, CanvasMode_EditWeldPoint, CanvasMode_EditMeshGradient, CanvasMode_FrameLinks, CanvasMode_Normal, CanvasMode_ObjImport, CanvasMode_Edit, CanvasMode_Magnifier, CanvasMode_Rotate, CreateMode, CanvasMode_EditGradient, MeasurementsMode, CanvasMode_Panning, CanvasMode_EditTable, BezierMode, CalligraphicMode, FreehandMode, CanvasMode_ImageImport, CellSelect, TableResize, CanvasMode_CopyProperties, CanvasMode_EyeDropper, ColumnResize, RowResize, CanvasMode_NodeEdit, and PanGesture.

virtual CanvasMode* CanvasMode::delegate ( )
inlinevirtual

main canvas modes dont have a delegate

Reimplemented in CanvasGesture.

virtual void CanvasMode::drawControls ( QPainter *  p)
inlinevirtual

Draws the controls for this mode and the selection marker. If viewmode.drawSelectionWithControls is true, also draws the selection contents first.

Reimplemented in LineMove, RectSelect, RulerGesture, ResizeGesture, CanvasMode_EditMeshPatch, CanvasMode_EditWeldPoint, CanvasMode_EditMeshGradient, CanvasMode_Edit, CanvasMode_EditArc, CanvasMode_EditPolygon, CanvasMode_EditSpiral, CanvasMode_NodeEdit, CanvasMode_FrameLinks, CanvasMode_Normal, CanvasMode_ObjImport, CanvasMode_Magnifier, CreateMode, CanvasMode_EditGradient, CanvasMode_EditTable, CanvasMode_ImageImport, MeasurementsMode, BezierMode, CalligraphicMode, FreehandMode, CanvasMode_Panning, CellSelect, ColumnResize, RowResize, TableResize, CanvasMode_CopyProperties, CanvasMode_EyeDropper, CanvasMode_Rotate, and PanGesture.

void CanvasMode::drawOutline ( QPainter *  p,
double  scalex = 1.0,
double  scaley = 1.0,
double  deltax = 0.0,
double  deltay = 0.0 
)

Draws an outline of selected items

void CanvasMode::drawSelection ( QPainter *  psx,
bool  drawHandles 
)

Draws the regular selection marker

void CanvasMode::drawSelectionHandles ( QPainter *  psx,
QRectF  selectionRect,
bool  background,
bool  insideGroup = false,
double  sx = 1.0,
double  sy = 1.0 
)

Draws the handles for the selection marker

void CanvasMode::drawSnapLine ( QPainter *  psx)

Draws an outline of selected items

void CanvasMode::updateViewMode ( CanvasViewMode *  viewmode)
virtual

Sets appropiate values for this canvas mode
