Ohhhh damn but WAIT! If I export it as .exe (standalone application) this does not happens
Its only when I use inside FlowStone environment that windows are frozen!

Why?!?!

Hey, I am not any master, especially in Flowstone..

Yep, I didn't understand your question, but my optimizations still apply if you want less CPU usage and smoother redrawing.

Did you try to change setting in Flowstone for navigator performance? Try using "minimal" it should give you better performance.

Hey Nowhk man,
The thing is, you have not actually made a redraw.
Delete the redraw module in the schematic u posted,
and what u r doing will still be the same.
Here is one way to draw->


What u r doing atm is using the architecture graphics to view within the environment.
As a user that is how it will behave on ur system unless you do something with your graphics card.

Cheer mate

Yeah, this fix the problem! Not sure why FlowStone doesn't use graphic card power even when refresh "frequent", but yes it seems to fix the responsiveness. Thanks.

Nowhk redraw.fsm

You are using an advanced FS version, and can't open the project (in FL, where I own FlowStone).
But yes man: I do a Redraw. If I remove the module, I can't see the cursors move anymore (at Tick25).

If I remove the Redraw module, they are stopped until I click with mouse on the working area (i.e. invoking a redraw), which is correct.

@Youlean: what's the real purpose (here) on using Redraw Area instead of Redraw.
For what I see, both Redraw and Redraw Area call the "draw" function defined for that View in the linked Ruby codes.

Even if I use one or the other, the def draw i,v function (defined inside the Ruby script that draw the waveform) is always called. This means that every cursor movement (processed by Tick25) redraw also the Waveform (which it shouldn't, since the data inside it changes only when I send to it different [F] values). Also graphically, I can't see any difference with Redraw or Redraw Area.

What are you tried to show to me here Youlean? I don't get it...

Said that: is there a way to avoid the calling of the ruby "draw" method using Redraw module? In this case, at every tick I should redraw only "Cursor" Area, not Waveform, even if both are linked to the same View:


As you can see, the float linked to the output of Ruby component is incrementing at every tick, because the def draw i,v function is being called (and I'm using Redraw Area; with Redraw its the same).

Unfortunately I don't understand Ruby.

Actually I have done some test and it seam that Redraw and Redraw Area are the same if you don't redraw smaller area than view.

If you wan't to optimize your redrawing of line your can do two things if waveform is static:
1. Redraw only area little before and after line. This is quite tricky to implement because of redraw skipping some sections...
2. Render waveform to a bitmap.

Or do both for ultimate performance!

Can you show to me a little example? Here looks always the same...

What do you mean with little area before and after line? The cursor?

Another idea I got is to link another prim to Waveform Ruby, and only when I got that value redraw cursor, and literally "return" the function (maybe with a flag variable) before redraw again the waveform (which the code is after the one of the cursor). Uhm...
