L1VM - launcher
L1VM - launcher
I did write a launcher for my GUI programs:
It shows the current time at the bottom. If you double click at the buttons you can launch the programs. I couldn’t use the normal GUI event loop, because it is a blocking call. So the time could not be updated. I do the mouse coordinations check in the program.
Here is the full launcher code:
// launcher.l1com
//
// SDL demos launch tool
//
#include <intr.l1h>
#include <misc-macros.l1h>

As you can see, the GUI buttons are created in about 7 lines of code!
With :sdl_get_mouse_state I get the current mouse state. If the mouse buttons are clicked and the current coordinate.
I do then check if the click was inside a button and launch the program.
