Tip: By Applying the OnMessage() Function, You Can Include Windows ToolTip Notes in Your AutoHotkey GUI Window Scripts to Add Hints and/or Instructions Which Pop-up When Mousing-Over the Controls
People might find some cleverly-designed AutoHotkey scripts confusing. Wouldn’t you like to add hints and tips which explain each control in your AutoHotkey GUI window? You can do just that with the ToolTip command and the OnMessage() function.
In the book AutoHotkey Applications, “Chapter Thirty-four: Pop-up Labels for All Your Programs (ToolTip Command)”, the Tooltip command highlights each control in an AutoHotkey GUI (Graphical User Interface) window. Use the ToolTip command to add helpful little informational notes to your AutoHotkey applications. Once you implement this tip, whenever you hover the mouse cursor over controls in an AutoHotkey GUI, the ToolTip command will identify the control’s function or give instant instructions (as shown below).
(Extra Tip: You can use this same technique with other non-AutoHotkey Windows application by identifying window and control names with Windows Spy or the WindowProbe.ahk script, then writing a short companion AutoHotkey script to work with the Windows program.)
