Title: How to Hide / Show the Main Menu of a Delphi Application
The TMainMenu Delphi component encapsulates a menu bar and its accompanying drop-down menus for a form.
The TMainMenu Delphi component does not expose the Visible property to let you show or hide the menu for a form programmatically, does it? It does not, but there is a way to hide the main menu for a Delphi form at run time. Here's how...
To assign a menu for a form, drop a TMainMenu on it (let's say it has "MainMenu1" for its Name property), add menu items and asign it for the Menu property of a form.
If you want to hide the menu programmatically, at run-time, just use this line of code:
//MainForm is the name of the form
MainForm.Menu := nil;
To show the menu again, simply reassign the Menu property for the form:
//MainForm is the name of the form
MainForm.Menu := MainMenu1;
That's it.
