cDrawer class.
A cDrawer derived class behaves like a Filter and extends its functionality by IDrawer methods, a Draw method and the coordinate space handling.
A cDrawer shares the Canvas with the containing Filter (based on cFilter) and handles Mouse and Keyboard events.
If the parent property is set, then the coordinate space is placed inside the referenced coordinate space. The parent property can contain the name of any drawer instantiated in the current filter graph. If no parent is set, the 2DDisplay coordinate space aka world is the parent.
tVoid ApplyMatrix | ( | const ucom::ant::iobject_ptr< disptb::graphicslib::dengar::ICanvas > & | pCanvas | ) |
This method is called before Drawing.
The purpose is to pass the matrix over to OpenGL, so that all further drawings will be scaled, rotated and moved like described.
pCanvas | [in/out] Pointer to the current Canvas object |
|
virtual |
This method is where the user code defines what is drawn on the canvas.
pCanvas | [in/out] Pointer to the current Canvas object |
tInt GetZOrder | ( | ) | const |
The ZOrder defines the order of drawing the objects, if there are in the same coordinate space level.
tBool IsVisible | ( | ) | const |
IsVisible() is not the same as IsActive()! If a drawer is invisible all Handlers will be called except the Draw method.
tResult OnDraw | ( | const ucom::ant::iobject_ptr< disptb::graphicslib::dengar::ICanvas > & | pCanvas | ) |
This method is called from the drawer manager to draw on the give canvas.
pCanvas | [in/out] Pointer to the current Canvas object |
tResult RegisterProperties | ( | ) |
Registers all defined property variables.

SetMatrix sets all parameter for the matrix to use in cDrawer::ApplyMatrix() Draw() don't need them because the matrix is applied before cDrawer::Draw() is called.
fTransX | [in] Translation in x direction |
fTransY | [in] Translation in y direction |
fScaleX | [in] Scaling in x direction |
fScaleY | [in] Scaling in y direction |
fRotate | [in] Rotation angle in degrees (CCW) |
