Rendering_options['ForegroundColor'] controls view.draw_text

thomthom

I just realised that the colour of view.draw_text is controlled by Sketchup.active_model.rendering_options['ForegroundColor'].

I don't understand at all why view.draw_text's colour is tied to this property. But at least you can know what colour the text is drawn in and adjust the background colour accordingly.

Ok - more oddity:

Styles -> Edges -> Color sets Sketchup.active_model.rendering_options['ForegroundColor'] from the SU UI.

Typing Sketchup.active_model.rendering_options['ForegroundColor'] = 'pink' into the ruby console changes the edge colours to pink.

But this from within the draw method of a Tool;


Sketchup.active_model.rendering_options['ForegroundColor'] = 'red'
view.draw_text( [520,220,0], 'Hello World' )
Sketchup.active_model.rendering_options['ForegroundColor'] = 'blue'
view.draw_text( [520,240,0], 'Foo Bar' )
Sketchup.active_model.rendering_options['ForegroundColor'] = 'black'

This does not update the Edge colour in the viewport. But Sketchup.active_model.rendering_options['ForegroundColor'] value is still updated.

In any case - this snippet let you draw text in the viewport and not mess with the edge style.


cache = Sketchup.active_model.rendering_options['ForegroundColor']
Sketchup.active_model.rendering_options['ForegroundColor'] = 'red'
view.draw_text( [520,220,0], 'Hello World' )
Sketchup.active_model.rendering_options['ForegroundColor'] = cache

I was wondering if the Edge colours would flicker when doing this - but I've noticed nothing. Maybe because I don't seem to be able to make any effect from within my Tool's draw method.

So can I link this to my bounding box question, and your and Chris F's replies, viz:

Objects to be moved are selected; a draw tool is used to trace or slightly offset the bounding box points with colour set as you say here. So when another selection is made there would be two boxes, say one fake red one, and the normal blue one for the destination. Both would be cleared on "Store route" or something.

Your post just got me thinking out loud (TOL), but if there are any comments that would be good.

Thanks

@ThomThom, ... last week when I was playing with the RenderingOptions, the controls in the SU dialogs did not reflect my changes until I called UI.refresh_inspectors. (I recall we had a discussion with TIG in the Observers thread, about whether these changes were temporary or permanent; I didn't realize at that time, that the dialogs needed to be refreshed.)

Regarding view draw changes, remember that ver 7.1 added View.refresh

.. what's that old saying?

Would that also refresh the edge colours? because they should be changing as well - but doesn't.

How does this differ from view.drawing_color="pink" ??

@ThomThom - I get an immediate change in the displayed edge color when I change rendering_options['ForegroundColor'].

You didn't turn of your DCs again did ya?

EDIT - Oh never mind, you mean within a Tool.

rendering_options['ForegroundColor'] is the Edge Colour setting.

view.drawing_color defines the colour used by view.draw and view.draw2d.

But view.draw_text doesn't use the colour set by view.drawing_color instead it annoyingly uses rendering_options['ForegroundColor'].

I would say this is a bug, as I would have tried using view.drawing_color=

Yea - it was only by accident I realised it used the edge colour. I thought it was fixed to black - like view.draw when y ou try to draw a face. But then I changed the viewport background and the text changed to white - as well as the edge colour.

Its a bug though. Introduced in the last couple of version of SU. I posted a bug to Google sometime back.

Previous to that, you could use drawing_color (as expected) to control text color.

Sketchup.active_model.rendering_options['ForegroundColor'] = color works fine for draw_text method.
However there is a very weird side effect, probably because the change of rendering is done within the draw method of a Tool.
This effect is that the SU main window seems to loose the focus, so that any call to UI.messagebox or UI.inputbox is blocked and does not show the dialog box (you have to press Alt to unlock this situation).

I did not find a way to circumvent this side effect.
