Problem with SetGradientColors()

[niocwy]

Hi everyone.

I'm trying to fade a texture control gradually, so decided to use :

SetGradientColors(integer orientation, number startR, number startG, number startB, number startA, number endR, number endG, number endB, number endA)

But it looks like the alpha parameters( startA and endA) are not taken into account, and I can't properly fade the texture. Anyone know why this is happenning ?

Or maybe this function is not supposed to work this way, but then I can't find a way to do what I want.

Haven't tried those. Only thing right off could be what the range for the alpha channel is on the transition.
If it's [0,1] and you treat as [0,100], it'll show as all on then off for example.

If you provide what you are actually doing that isn't working we can be of more help.

It's using the [0,1] range.

I actually got it to work. The problem is not with the function, it works fine. Looks like there's two issues to consider here :

- first, if you're changing the alpha of a parent control using SetAlpha(), then the alpha values set by SetGradientColors() gets overriden.

- also, I was calling the function early in the initialization of my addon, but when I call it at runtime with zgoo, then it works. Considering I was doing this with a test control on which I didn't touch the alpha values of any parents on initialization, I guess that when the UI is loaded something must happen that changes the alpha of the control or its parent to 1.
