This will let you create a box and position it somewhere on the screen.
|
|
The text_buffer is a pointer to a character array and needs to be as long as
|
|
AT LEAST MAX_CHARS + 1.If the text_buffer is smaller, it will crash if user
|
|
types more characters than what will fit into the text buffer.
|
|
|
|
Allocating buffer space automatically so that programmer can be carefree now.
|
|
This also automatically adjusts the size of edit box so that it can hold enough characters.
|
|
|
|
All you need is :
|
|
|
|
tlx,tly = Coordinates of the beginning of the edit box.
|
|
max_chars = Limit of number of characters user can enter into edit box.
