Scale to use when calculating drawing stuff
TInt iZoomFactor;
// Precalculated drawing stuff
CFont* iBorderFont;
CFont* iTileFont;
TRect iBoardRect; // Board area
TRect iTopBorder; // All of top border
TRect iBottomBorder; // All bottom border
TRect iLeftBorder; // Left border, excluding top and bottom
TRect iRightBorder; // Right border, excluding top and bottom
TInt iTileSize; // Side of tile (1/8th board area)
TInt iBorderSize; // Size of border
};
The first group of public functions (commented as 'Construct/destruct/ setup') is called by the
app UI to create the view. The remaining public functions are for use by the controller, to tell
the view to respond to user commands or engine data changes.
The first group of private functions (commented as 'From CcoeControl') overrides the control
base class functions to draw the view, and to handle pointer and key events, respectively.
The remaining private functions implement various parts of drawing the view.
The private data stores parameters passed into the view when it is set up, and data, such as
fonts and coordinates, is required to draw the view. iFleet is the model and iCmdHandler
is the controller in the MVC sense. So this control works as the V part of a well-structured
MVC trio. The fleet view allows a cursor to be displayed, controlled by iCursorOn and (x, y)
coordinates. Finally, the view can be zoomed to a size that is (iZoomFactor/1000) times
the default size (more on this later).
9.4.1 View Construction
The view's main setup function is ConstructL():
void CFleetView::ConstructL(const TRect& aRect)
{
// window setup
CreateWindowL();
SetRect(aRect);
// set cursor
SetCursor(0,0);
// set zoom factor
SetZoomL(1000);
// activate control as ready for drawing
ActivateL();
}
