Try this version for 2.9.
name it qtdragon_hd.ui
put it in YOUR CONFIG FOLDER/qtvcp/screens/qtdragon_hd/

Hi Chris,

yes that worked and it loaded the screen, thanks.
 

Excellent let me know of any bugs please.

Hi Chris,

I am trying to add a grid to the 3d graphics before i start with adding a 3d model of the machine, same grid with the qtplasmac, i checked its code and added the lines(i think that its related with drawing a grid in the viewport) to the qtdragon_hd_handler.py(lines with the + signs next to line numbers in the attached screenshots) but i can not see a grid in the viewport. as u know i dont know the programming language i am just copying and pasting, i also added a doublescale box in qt designer, i can see the grid size as 50 in startup as i entered in the code but there is no grid still in 3d graphics.

have u tried adding a grid to 3d graphics before or do u know how to do it? Thanks in advance.

Hakan

 

I believe the grip only shows in z view. It should work without coding. Might have ro set grid bit it did work.

in qtplasmac it shows in z view and perspective view,

what u mean by it should work without coding, is there a way to turn it on or set in qtdragon_hd?

Sorry for cryptic message - I am away from home for work.
I did not know that QtPlasmac was patched to show a grid in P view - those plasma guys are very crafty!
I also didn't realize QtDragon had no builtin way to show grids

(I assume your gcode graphics widget is called gcodegraphics in designer)

To get XYZ grids to show you must set a grid size:
self.w.gcodegraphics.grid_size = 1
setting the grid color is possible (Red,green,blue):
self.w.gcodegraphics.colors = (1.0, 1.0, 1.0)
add those to bottom of  init_widgets() function.

to get grid in perspective too require patching.

add to bottom of  init_widgets() function:I think I should modify the underlaying code so the patching is not necessary - on the todo list.

Thanks for the detailed reply Chris,

I disabled all the lines i added to the code and added some of your code under init_widgets() function and put the rest where other functions or patches are defined, when i run the linuxCNC i got the attached error, did i miss something?

Hi again,

i got it, there was an indentation error, fixed it also changed self.w.gcodegraphics.colors = (1.0, 1.0, 1.0) to self.w.gcodegraphics.color = (100, 100, 100) so i have a grid on perspective view now

Thanks Chris
