TFindDialog.Execute function
Displays the dialog form and responds to button clicks.
Declaration
function Execute: Boolean; overrideFunction result
True if the dialog was successfully configured and displayed in the method.Description
Execute is an overridden
Boolean function used to
display the internal dialog form and respond to button clicks on the form.
Execute reimplements the method defined in the ancestor class, and does
not call the inherited method.
If a TForm instance already exists in the dialog class, it is reused. If not, CreateForm is called to create and configure the TForm instance displayed for the dialog. The return value is False if a TForm instance was not successfully created in CreateForm.
When a valid form exists for the dialog, it is positioned on the screen by calling CalcPosition. SetFormValues is called to transfer property values in the class instance to the dialog form. The Title, HelpContext, OnClose and OnShow properties in the form are updated and its Show method is called to display and execute the form. Values from the Height and Width properties in the form are stored in the dialog class for use as the default size.
The return value is True if the form was successfully configured and displayed in the method.
Use the OnFind, OnHelpClicked event handlers to perform actions needed when either the Find or the Help button on the dialog form is clicked. The Cancel button calls CloseDialog when the button is clicked.
