virtual dword GetAccessKeys() const
Ctrl should use this method to signal presence of access keys. Access keys are keyboard keys that can be used to access or activate dialog functions when pressed together with Alt key. They can be defined by application designer (usually using & or \b in labels), or they are automatically synthesized using AssignAccessKeys method. If Ctrl (of one of Ctrls in its child tree) has some access keys and those keys are letters (in range 'A' - 'Z'), they should be returned as bit value using AccessKeyBit function. Other access keys should be indicated by bit 0 (that means, by binary or of 1 to result). Default implementation returns 0.

virtual Size GetStdSize() const
This method should return maximal size of Ctrl.

|
Return value |
true if Ctrl should be painted as enabled. |
virtual int OverPaint() const
This method can returns non-zero number that represents paint extension margin of view area - Ctrl can paint inside this margin despite that fact that it does not belong to view. This is useful to represent some specific skinning effect (like glare around the button). Default implementation returns zero.

For transparent Ctrl returns set of frame areas that should be painted as transparent.

Vector of opaque view areas. |
virtual void Close()
Closes top-level Ctrl. If Ctrl is not top-level, has no effect. If it is and is open in host GUI (either as pop-up or as TopWindow), it should close it. Default implementation closes. TopWindow overrides this method to break modal loop instead of closing if modal loop is performed for it.

Used for Ocx control implementation.
virtual void SetData(const Value& data)
Sets the new value to the object. Default implementation is void.
virtual Value GetData() const

Typical use is when user pressed OK button. If any Ctrl of dialog returns false, OK is canceled.
Typical implementation of this method should test whether current state of Ctrl (its edited value) matches requirements. If it does, it should finish editing, accept edited value and return true. Otherwise it should return false,
|
Return value |
Ctrl should return true if it successfully finished editing, false otherwise. |
virtual void Reject()
This virtual method is called when Ctrl should abort editing, discarding edited value. Default implementation calls Reject for all child Ctrls.
