Processes a dialog key.
protected:
virtual bool ProcessDialogKey(System::Windows::Forms::Keys keyData);
protected virtual bool ProcessDialogKey (System.Windows.Forms.Keys keyData);
abstract member ProcessDialogKey : System.Windows.Forms.Keys -> bool
override this.ProcessDialogKey : System.Windows.Forms.Keys -> bool
Protected Overridable Function ProcessDialogKey (keyData As Keys) As Boolean
Parameters
Returns
true
if the key was processed by the control; otherwise, false
.
Remarks
This method is called during message preprocessing to handle dialog characters, such as TAB, RETURN, ESC, and arrow keys. This method is called only if the IsInputKey method indicates that the control is not processing the key. The ProcessDialogKey simply sends the character to the parent's ProcessDialogKey method, or returns false
if the control has no parent. The Form class overrides this method to perform actual processing of dialog keys. This method is only called when the control is hosted in a Windows Forms application or as an ActiveX control.
Notes to Inheritors
When overriding the ProcessDialogKey(Keys) method in a derived class, a control should return true
to indicate that it has processed the key. For keys that are not processed by the control, the result of calling the base class's ProcessDialogChar(Char) method should be returned. Controls will seldom, if ever, need to override this method.
