vanilla.Slider width/height

[jesentanadi]

Hi, I'm updating an old script and I'm having some problems with Slider direction. Wondering if it's related to the comments on this commit and if there's a good way around it for now.

This code: self.w.xHeightSlider = Slider((x+2, row2+22, 194, 25)...

produces this:

But if I flip the width/height, it looks like my x,y coordinates also don't work:

Seems like something like self.w.xHeightSlider = Slider((x+2, row2+22, 194, 195) works, but I'd have to decrease the y value a lot:

I can't set the width to -10 because there are more UI elements next to the slider.

Thanks!

@gferreira Thanks for helping!

hmm, I'm getting a horizontal slider in Demo1

you are right — it was a typo :) (fixed in the code sample, thanks!)

I get the same results (macOS 10.13 / RF 3.2b):

@gferreira hmm, I'm getting a horizontal slider in Demo1—although as a user, I think this is what I would expect, since I'm specifying the width first.

In both these cases, it seems right that the current _isVertical() would return False when w == h (when both are -10) and True when 180 > -10, so if _isVertical() returns w < h instead, then the Slider would be horizontal in both cases.

I've opened an issue, so we'll see.

@jesentanadi good point. looking closer into it, I see that the Slider gets a different orientation if the width is specified as a positive or negative integer:

from vanilla import Window, Slider

class SliderDemo1(object):

    # width as negative number (relative to parent object)
    # slider is horizontal = CORRECT

    def __init__(self):
        self.w = Window((200, 100), title='demo 1')
        self.w.slider = Slider((10, 10, -10, -10))
        self.w.open()

class SliderDemo2(object):

    # width as positive number (absolute value)
    # slider is vertical = WRONG!

    def __init__(self):
        self.w = Window((200, 100), title='demo 2')
        self.w.slider = Slider((10, 10, 180, -10))
        self.w.open()

SliderDemo1()
SliderDemo2()

I think it really is a bug, and we need to reopen issue #58…

@gferreira That works, thanks!

I'm on macOS 10.13, but running RF3.1.

I'm still confused about why, in your case, it works without the explicit setVertical() if self._isVertical() returns True when w > h.

some background info: How can I make a vertical slider?

[gferreira]

hi. I also came across this bug some time ago… you can temporarily fix it like this:

self.w.slider.getNSSlider().setVertical_(True) # or False

which version of macOS are you running? which version of RF3?

I think this problem happens only in macOS 10.12 (??) – it’s working fine for me on macOS 10.13 using the latest 3.2 beta.
