Internal Functions

Functions that will defined for use internally by the control will be:

_SB_WndProc             PROTO :DWORD, :DWORD, :DWORD, :DWORD
_SB_Init                PROTO :DWORD
_SB_Cleanup             PROTO :DWORD
_SB_Paint               PROTO :DWORD
_SB_PaintBackground     PROTO :DWORD, :DWORD, :DWORD, :DWORD, :DWORD, :DWORD
_SB_PaintText           PROTO :DWORD, :DWORD, :DWORD, :DWORD, :DWORD, :DWORD
_SB_PaintBorder         PROTO :DWORD, :DWORD, :DWORD, :DWORD, :DWORD, :DWORD

These internal functions are the core functions that handle the main processing and painting of our SimpleButton control.

In addition, we will define a few other internal helper functions for use in this control. In my own development projects I combine the functions next into a library or framework for easy re-use, but I have recreated them here and included them in the SimpleButton.asm file just for ease of use and clarity in covering the features in the control. The internal helper functions are:

__AllocMemProperties     PROTO :DWORD, :DWORD, :DWORD
__FreeMemProperties      PROTO :DWORD, :DWORD
__GetIntProperty         PROTO :DWORD, :DWORD
__SetIntProperty         PROTO :DWORD, :DWORD, :DWORD
__GetExtProperty         PROTO :DWORD, :DWORD
__SetExtProperty         PROTO :DWORD, :DWORD, :DWORD

These functions are briefly covered later on (see Inside Our Control) and some more detail can be found in the Control Properties section.
