PA_Dial4DSetReal (dialog; variable; newValue)
Parameter | Type | Description | |
dialog | PA_Dial4D | Dialog reference | |
variable | char* | Name of the variable to access | |
newValue | double | New value of the variable |
Description
The routine PA_Dial4DSetReal sets the value of a variable whose name is variable to the value newValue. This command is preferred to the PA_Dial4DSetVariable call because it handles the type conversion for the developer.
By default, variable needs to be a null terminated C string. If you have previously called PA_UsePStrings, you must pass a Pascal string to the command.
By default, variable needs to use Macintosh characters set on Macintosh, and ANSI characters set under Windows. You can call PA_UseMacCharacters or PA_UseAnsiCharacters to specifically use Macintosh or ANSI characters.
In order that 4th Dimension knows it must redraw the dialog, all PA_Dial4DSetxxx routines must be squared by calls to PA_Dial4DMarkVariable and PA_Dial4DRestoreVariable.
