name a drawLine?

[msepsis]

I have a custom component with a drawn element (small square) that moves horizontally depending on the value of a knob (named in lua – “sw1position”).

I would like the square to be “erased” or hidden if the value of a combobox (named in lua: “waveform”) changes.

Is there a way to name a drawLine (below) so that you can later set its visibility, or change its color? Here’s a snipit of what is being drawn on the customComponent and how it’s drawn, very basic:


sw1position = panel:getModulatorByName("Wave 1 Startwave"):getModulatorValue()
graphics:setColour (Colour(0xff55BBff))
graphics:drawLine ((sw1position*25)+3, 0, (sw1position*25)+3, 5, 5);


This works fine, I basically just want to then “hide” the 5×5 “drawLine” (actually a small, blue box) if my “waveform” combobox’s value changes. ..

Any other suggestions welcome.. I’m giving a few alt workaround a shot right now but being able to name a drawLine would be ideal in this situation so I could manipulate the drawLine depending on the value of various modulators.

you can’t name lines 🙂 those are not components. you can write a function that will take 2 parameters, one the graphics context and the other one a variable that will determine how the line is drawn, then just call that function with those two parameters wherever you need. have a look at the rendering demo, there is a lot of examples on how to do that.
