Compiler/MSP430F5659: Help with assigning a variable button to a button structure using the Graphics Library

Hi- I'm using the Graphics Library in a Project with an MSP430 and a graphics display. This is more of a software question then an issue. I have a bunch of Button structures defined and I would like to modify them without specifying a particular button. For example;

Graphics_Button But_Menu1= { 135, 250, 0, 30, 2, 0, ClrBlack, ClrWhite, ClrLightGrey, ClrWhite, ClrWhite, 154, 8, "MESSAGE 1", &g_sFontCmss18b };
Graphics_Button But_Menu2 = { 260, 375, 0, 30, 2, 0, ClrBlack, ClrWhite, ClrLightGrey, ClrWhite, ClrBlack, 288, 8, "MESSAGE 2, &g_sFontCmss18b };

//in program instead of this
But_Menu1.fillColor = ClrLightBlue;

// I would like to use a variable mychoice to choose either Menu1 or Menu2?

mychoice.fillColor = ClrLightBlue;
//how do I do this?
//Thanks

I'm not familiar with this graphics library. But I have a suggestion to consider.

Make the variable mychoice a pointer. Here is some code which illustrates how it could work ...

Graphics_Button *mychoice;  // pointer

// many lines later

if (/* some condition here */)
   mychoice = &But_Menu1;
else
   mychoice = &But_Menu2;

// many lines later

mychoice->fillColor = ClrLightBlue;

Thanks and regards,
