Overview

This code snippet demonstrates how to draw a custom border around a GUI component.

This snippet can be self-signed.


Header file

Override the CCoeControl::Draw method.

// From CCoeControl
public:
// Draws the view.
void Draw(const TRect& aRect) const;


Source file

Define the color of the border:

#define KBorderColor    TRgb(180, 0, 0)

The drawing is implemented in the CCoeControl::Draw method so that the border is drawn every time the view is drawn.

// Draws the view.
void CAppView::Draw(const TRect& aRect) const
{
CWindowGc& gc = SystemGc();
 
// Draw the border around the component (iComponent)
gc.SetBrushColor(KBorderColor);
TRect rect = iComponent->Rect();
// Enlarge the border rectangle so that it becomes visible. Without this,
// the rect would only contain the innards of the component, which will
// be obscured by the component itself.
rect.Grow(3, 3);
gc.DrawRect(rect);
}
