Documentation: Color switching for XP Pen

[jahagirdar]

From the man page it is not clear how to implement color switching with XP-Pen Tablet.
My configuration file is

"red Pen" = PEN (size=5 color="red");
"blue Pen" ="red Pen" (color="blue");
 
"default"= "red Pen";
"default"[SHIFT]= "blue Pen";
"10 inch PenTablet Pen (0)"  = "red Pen";
"10 inch PenTablet Pen (0)"[SHIFT]  = "blue Pen";

I am executing the following commands in my terminal.

xinput --create-master mpx 
xinput --reattach 16 18
gromit-mpx
gromit-mpx --toggle 0

My expectation was hitting the shift key and scribbling with the tablet pen will change color. it does not.
Looking at the bug report I can see other are using their tablet with colors. but there was no reference instruction or configuration file :(

Hi @jahagirdar, your expectation is right, it should work. I can only offer some ideas why it would not:

• Is the keyboard you're pressing Shift on paired with the MPX master device that is the pen?
• You might also be running into Modifier keys like Shift, Ctrl, Alt don't always work under XWayland #106 when running under Wayland.

The Physical keyboard is on a different master... "Virtual core keyboard"

I checked the keys on XP-Pen tablet with xev. They generated the following code
Key1:
Key2:
Key3: 'b'
Key4: 'e'
Key5: '^Z'
Key6: '^S'
Key7: '^Z'
Key8: '^Y'
Can this be used in the configuration file to change the pen behavior?

This is the configuration I use with my XP-PEN and works relatively OK.

"red Pen" = PEN (size=4 color="red");
"blue Pen" = "red Pen" (color="#4682B4");
"yellow Pen" = "red Pen" (color="#FE8B1B");
"green Marker" = PEN (size=5 color="green" arrowsize=2);

"Eraser" = ERASER (size = 80);

"XP-PEN STYLUS Pen (0)" = "red Pen";
"XP-PEN ERASER Eraser (0)" = "Eraser";

"default" = "red Pen";
"default"[SHIFT] = "blue Pen";
"default"[CONTROL] = "green Marker";
"default"[META] = "yellow Pen";
"default"[Button3] = "Eraser";

OK, closing then.
