arrow keys not working when window is resized.

in General Discussion • Other • 9 months ago

Hey, updating to Processing 2.0 to check out the window resizing stuff which seems to work okay so far.

Only weirdness is that after I resize the window all the actions I have coded to the arrow keys are not working.

This seems to only effect P2D and P3D image modes, I can get it working with the standard image mode (ie just size(500,500)), but it is not really a long term fix since it makes the text look strange and it will get bogged down when I get into more complicated imagery (it is a drawing program).

I have not posted any code here since it is just a drawing program I had just opened from my previous version of Processing (1.5) to see if it would work.

Do I need to include/update some other function?

Do the keys work after clicking on the sketch area? It might be just a focus issue. Strange, but with OpenGL, it is hard to tell.

" it makes the text look strange"
In what way?

it doesn't seem to be a focus issue since all the other keys (ie a, b, c...etc. or keys that aren't part of the "coded" conditional). The keys are working fine, but after the app is resized in P2D, P3D or OPENGL the arrow keys only stop responding. Just another note it was working totally fine in Processing 1.5, I'm updating mainly to stay current and because the window resizing is improved.

The text looks thinner than it should, it looks smooth enough but seems "less anti-aliased" (a colloquialism I use is that it looks "crispy") than in P2D, P3D, OPENGL modes if that makes sense. I can ultimately live with this and the rendering of the lines actually looks better, but I have some big ArrayLists to store drawings so it starts to get bogged down once there is a lot of stuff going on.

I haven't posted any code because the keyPressed() section is fairly standard. see below:

if(key == CODED)

{

if(keyCode == RIGHT)

{

the_dist += 10;

}

if(keyCode == LEFT)

{

if(the_dist > 0)

{

the_dist -= 10;

}

if (keyCode == UP)

{

speed++;

}

if (keyCode == DOWN)

{

speed--;

}

It might be an issue with OpenGL. If you can create a simple sketch reproducing the behavior (both arrow keys and thinning), show it here, and if nobody say you made some error (I am not a specialist of OpenGL myself), it can be interesting to report it as a bug (unless andres reacts here first!).
