Dear Thunor,

Here is a screen shot. The last hslider (4) and vslider (4) show this behaviour. Is that intended?

With kind regards,

The two sliders you show are made by function funcscaType3Create.
I have been able to make them full sliders by modifying the scale-max value in the function.
But I am almost sure that that function was made for a specific purpose.
So I would like to see explanation of it's use to clarify it.

Hi guys

I'm guessing it's a theme issue.

See "fill-level", "restrict-to-fill-level" and "show-fill-level" if you want to know more about it.

Nice (or actually not nice) to see that your vertical markup is all over the place, similar to mine Confused

You also seem to have missing marks.

[EDIT] I've just noticed that my Polished-Blue screenshot has missing marks too, so I'm guessing that that's a theme issue also (there should be three marks on the 2nd and 3rd scales only, the 3rd scale being staggered top/bottom, left/right).

I think it's possible that currently the markup isn't very stable which would explain why I haven't yet found an application that's using it.

Regards,
Thunor

My window looks like this and the marks are there on the sliders.
But I think the question was to why the function Type3Create does not let the slider pointer go from top to bottom of the slide.

thunor,
thank you for the explanation.
As a test, I changed restrict-to-fill-level in the type3create function from true to false and was able to achieve a full range slider that still remembered it's original position when the refresh button was clicked.
So thank you again.

Understanding helps greatly in writing scripts that utilize these new features you are working on.

Somebody asked me how to use the new features whilst still maintaining compatibility with older versions of Gtkdialog. I guess the way to do it is to check the version of the binary, but it's complicated by the fact that it went from 0.59.8 to 0.6.0, so I came up with this:

The hscale and vscale widget example has been driving my crazy getting it to display right.
So in my usual bunbling way, I added an item to the type2 function.
My result although not correct, does display correctly. Why does it work? Evidently the last item in the type2 function gets placed incorrectly.

I am testing the <hscale> widget in Pmusic 2, and I am having some trouble.

The default signal is "value_changed" which activates itself when slider is moving. My problem is that it does run <action> both when it is refreshed (<action>refresh:HSCALE</action>) from another widget, and when user moves it. My hope is to show progress when refreshing, and jump-in-track-time if user moves the slider. Is this possible? I checked the gtk-scales signals, but couldn't find any answer.

Thank you
Sigmund

I want to make sure I understand the parameters passed to the type2 function in the hscales and vscales example.
What I have come up with is
$2 is the scale type being either h for horizontal or v for vertical
$3 is the slider width of the scale
$4 is the height of the scale
$5-$7 are the position of the markup left, right, top, bottom, on the slider
For a vertical slider, markup position parameter values passed to function type2 are
0 being left of slider, 1 being right of slider
And for a horizontal slider, markup position parameter vales passed to function type 2 are
2 being top of slider, and 3 being bottom of slider.

Now if this is right, why are the markup tags on the vertical scale being displayed in the wrong place on the slider?
Could it be that gtk2 or pango are not receiving the parameters in a format they expect?

Also, if one plays with the example I posted that displays right and changes any of the parameters for the vscale, it will not display correctly.

I guess I will have to dig deep to solve it.

I am making progress Smile

block-function-signals="true" works great - thank you.
But I still have some issues Very Happy

I am trying to control the <action> of hscale.

1.)
With the code below I have to click the mouse-middle-button to get the correct value of $PROGRESS. Left click always return 0 or 100.

2.)
The action is executed when mouse is pressed down (not released as I expected). This makes it impossible to drag the slider to a given position and then execute the <action>. I tried to include <action signal="released"> as in the <button> widget, but it failed.
