PA_Dial4DGetReal (dialog; variable) double
Parameter | Type | Description | |
dialog | PA_Dial4D | Dialog reference | |
variable | char* | Name of the variable to access | |
Function result | double | Value of variable |
Description
The routine PA_Dial4DGetReal gets the value of a variable whose name is variable and returns its value as a double. This command is preferred to the PA_Dial4DGetVariable call because it handles the type casting 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, varName needs to use Macintosh characters set on Macintosh, and ANSI characters set under Windows. You can call PA_UseMacCharacters or PA_UseAnsiCharacters to use specifically Macintosh or ANSI characters.
