Parameters
| Name | Explanation |
|---|---|
| DC | The device context |
| ALeft, ATop | The x, y coordinates of the top left corner of the rectangle |
| ARight, ABottom | The x, y coordinates of the bottom right corner of the rectangle |
| ARect | The x, y coordinates of the rectangle |
| UnitMode | Sets the units for the ALeft, ATop, ARight, and ABottom parameters (vikPrinterPixel: units in pixel; vikPrinterMM: units in 0.1mm) |
Use either ALeft, ATop, ARight, ABottom or ARect.
Return Value
Returns True if successful. Returns False if unsuccessful.
Explanation
The DrawFocusRect method draws a rectangle in the style used to indicate that the rectangle has the focus.
Because DrawFocusRect uses XOR function to draw the rectangle, calling it a second time with the same rectangle removes the rectangle from the screen.
This function draws a rectangle that cannot be scrolled. To scroll an area containing a rectangle drawn by this function, call DrawFocusRect to remove the rectangle from the screen, scroll the area, and then call DrawFocusRect again to draw the rectangle in the new position.
To draw the rectangle, the BrushStyle and BrushColor properties must be set.
If the UnitMode parameter is vikPrinterPixel, then the ALeft, ATop, ARight, ABottom, (or ARect), X1, Y1, X2, Y2 parameters are in pixel units.
If the UnitMode parameter is vikPrinterMM, then the ALeft, ATop, ARight, ABottom, (or ARect), X1, Y1, X2, Y2 parameters are in 0.1mm units.
Differences between the ImageKit7/8/9/10
In VCL the constants contain a "v". In ActiveX, the constants
are: ikScreen, ikPrinter, ikMemoryHandle.
Methods that pass a TRect type have been added.
