Time scale along Panel edge

wxPython Users
1

I want to layout a time scale along the edge of a panel, say, the length of the panel is equivalent to 30 seconds, and I want to show tick marks at 1 second intervals, with beginning and end points labelled. Something like you could do with a slider control.

Is there a specific wxWidget that could do this, or do I need to write the code myself in an OnPaint method? Thanks for suggestions.

Best regards,
Tim Grove

What else do you want in that panel?

wx.lib.floatcanvas could make this easy, particularly if you want to be able to zoom it, but it depends what else you want there.

Hi Chris,

Nothing specific at the moment, just a general question to see if there
was anything such as a "ruler widget" somewhere within wxPython that
already did this, that I haven't discovered yet. Thanks for the response!

You might want to take a look at my implementation of RulerCtrl:

It might do what you are looking for.

Hi Andrea,

I'm giving your RulerCtrl a try. Can the position of an indicator (and the position of the thin line associated with it) be set programmatically, or only by mouse dragging?

I've also found that when I'm dragging the indicator with the mouse and I move the mouse off of the indicator before I've finished dragging, the line remains drawn on the window. I can end up with several lines drawn this way all over the window! This also seems to happen in the demo as well.

Best regards,
Tim
