HI all,

How to change the glbuttons.png display array?

I try to do this:

First,I edit the 'glbuttons.png' width 512px height 2048(default 1024),now display this:

OK,you can find the red color font 1,2,3,4 . this is I want to append the buttons images.

Second,I add the button code in sceneView.py ,

the code '32' is the 'glbuttons.png' array number.

Now,when i debug this ,the ckButton's images cannot display,How can I fix it?

It's easier to replace the 5 unused spots, else you need to dive into the glButton code to account for the changed texture size.

tks Daid,

I found glButton code,but how can I update the texture size in code ?The glButton code is in cura/gui/openglGui.py lines 452 the draw functions.like this:

because i want to append the 'glButtons.png' behind,it look like 4*9 array list. but when i try debug this,the ckButton's images cannot display also.

It's OpenGL code, and OpenGL likes textures with powers of 2. So when you change the texture size, it's best to keep it at a power of 2.

Also, this is the code that does the actual drawing:

tks Daid,

when I keep it at a power of 2,so how can I update the code if I want to append array as 4*10?

4*10 is not a power of 2.

4*10 is not a power of 2.

 

oh...4*16 is a power of 2. and i edit the

ty = float(int(texID / 4)) / 16

tsy = 0.0625

but the button display white box also

White box most likely means the texture is not loading properly. Do not know what you used to edit it, but you might need to disable "progressive PNG" when saving the png file.

tks Daid,

now the button display ok,but when load a STL file to cura,the button display like this:

how can i fix it?
