NAME: CONTROL_WINDOW
|
||
|
|
|
||
|
|
SYNOPSIS: Control window class
|
||
|
|
|
||
|
|
INTERFACE:
|
||
|
|
CONTROL_WINDOW() - constructor.
|
||
|
|
|
||
|
|
QueryCid() - return the CID private member.
|
||
|
|
|
||
|
|
ClaimFocus() - focus the current window
|
||
|
|
|
||
|
|
QueryFont() - return the current font handle
|
||
|
|
SetFont() - sets the current font, optionally redrawing
|
||
|
|
the control. Takes either a font handle or
|
||
|
|
a logical font object
|
||
|
|
|
||
|
|
SetControlValueFocus()
|
||
|
|
Redefines the CONTROL_VALUE::SetControlValueFocus to simply call
|
||
|
|
ClaimFocus.
|
||
|
|
|
||
|
|
Validate() - checks the control's contents for validity.
|
||
|
|
IndicateError() - indicates erroneous user input
|
||
|
|
|
||
|
|
PARENT: WINDOW, CONTROL_VALUE, FORWARDING_BASE
|
||
|
|
|
||
|
|
USES: CID, FONT
|
||
|
|
|
||
|
|
NOTES:
|
||
|
|
At its construction, each control checks its owning window
|
||
|
|
(to which it forwards all error reports and queries) to see
|
||
|
|
if it failed.

which adopts the embedded scrollbar of another control, e.g.
|

|
|
that of a MLE.
