Button Hover --> Function

#1 Torque does have tooltips for buttons already built in, so that would probably be the best place to start.

#2 In addition to built-in tooltips,
there's also onMouseEnter(), onMouseLeave(), and relatedly in this resource, onMouseEnterBounds() and onMouseLeaveBounds().

#3 OnMouseEnter doesn't appear to do a thing. I named one of my GuiBitmapButtonCtrls "createInternet" and then made a function that looked like this:

function createInternet::onMouseEnter()
{
   echo("LOL!");
}

Nothing echoed when I moused over it. Unless I'm using/calling it incorrectly.

But that resource looks nice. Thanks!

#4 I'm assuming you mean you want a script function to be called on enter/leave. It's easy enough to add. The file you want to edit is guiButtonBaseCtrl.cc/h

Add to the .h file a string for the command to run on enter/leave

StringTableEntry mMouseEnterCmd;
StringTableEntry mMouseLeaveCmd;

In the GuiButtonBaseCtrl constructor, initialise both of those

mMouseLeaveCmd = mMouseEnterCmd = StringTable->Insert("");

Then hook up the commands as script fields in initPersistFields

addGroup("MouseEvents");    
      addField("onMouseEnter",     TypeString,    Offset(mMouseEnterCmd, GuiButtonBaseCtrl));
      addField("onMouseLeave",     TypeString,    Offset(mMouseLeaveCmd, GuiButtonBaseCtrl));
   endGroup("MouseEvents");

Then call the script handler if it exists at the end of onMouseEnter and onMouseLeave

if ( mMouseEnterCmd[0] )
   {
      char buf[16];
      dSprintf( buf, sizeof( buf ), "%d", getId() );
      Con::setVariable( "$ThisControl", buf );
      Con::evaluate( mMouseEnterCmd, false );
   }

(The on mouse leave code is the same, just switch enter for leave)

Then in script, you just need to enter the command in the onMouseEnter and onMouseLeave fields

// .... inside your button control 
   onMouseEnter = "echo(\"mouse enter event\");";
   onMouseLeave = "echo(\"mouse enter event\");";
   // ... rest of button fields

#5 Brilliant!

Works like a charm. Thank you so much.

#6 Edit: Nevermind, stupid error.
