Thanks, it is working.

I tried that, but it did not work correctly. It did not give the wanted result.

#geUserArea.DrawSetTextCol(c4d.Vector(255,255,255), c4d.Vector(128,128,128))
#geUserArea.DrawSetPen(c4d.Vector(255,255,255))

Background should alternate and the foreground should be white.
I tried a lot of color, but could not get the correct combination.

I changed following line. LV_TREE to LV_USER

        #layout.SetLong(ID_NAME, c4d.LV_TREE)
        layout.SetLong(ID_NAME, c4d.LV_USER)

And in DrawCell() I added the handling of ID_NAME

    def DrawCell(self, root, userdata, obj, col, drawinfo, bgColor):
        """
        Draw into a Cell, only called for column of type LV_USER
        """
        
        if col == ID_NAME:
            name = "Pim: " + obj.otherData
            geUserArea = drawinfo["frame"]
            w = geUserArea.DrawGetTextWidth(name)
            h = geUserArea.DrawGetFontHeight()
            xpos = drawinfo["xpos"]
            ypos = drawinfo["ypos"] + drawinfo["height"]
            drawinfo["frame"].DrawText(name, xpos, ypos - h * 1.1)
            
        if col == ID_OTHER:
            name = obj.otherData
            geUserArea = drawinfo["frame"]
            w = geUserArea.DrawGetTextWidth(name)
            h = geUserArea.DrawGetFontHeight()
            xpos = drawinfo["xpos"]
            ypos = drawinfo["ypos"] + drawinfo["height"]
            drawinfo["frame"].DrawText(name, xpos, ypos - h * 1.1)

This is the result:
Initially all white:

After adding all black:

So, how can I set the text color?

I want a treeview (more a treeList) with two LV_USER fields and no LV_TREE field.
I started with the given example and I succeed, but the text colors are incorrect.
Initially all white, but after a click all black.
How can I set the text foreground and background color?
The background color is actually defined by the usergui.
customgui.SetBool(c4d.TREEVIEW_ALTERNATE_BG, True) # Alternate background per line.

I tried setting the text color using GeUserArea.DrawSetTextCol(c4d.Vector(0,0,0), c4d.Vector(128,128,128)) and GeUserArea.DrawSetPen(c4d.Vector(255,255,255)) but no success.

Here some code.

        customgui.SetBool(c4d.TREEVIEW_HAS_HEADER, True) # True if the tree view may have a header line.
        customgui.SetBool(c4d.TREEVIEW_HIDE_LINES, False) # True if no lines should be drawn.
        customgui.SetBool(c4d.TREEVIEW_MOVE_COLUMN, True) # True if the user can move the columns.
        customgui.SetBool(c4d.TREEVIEW_RESIZE_HEADER, True) # True if the column width can be changed by the user.
        customgui.SetBool(c4d.TREEVIEW_FIXED_LAYOUT, True) # True if all lines have the same height.

@pim said in Profiling Python Plugins:

@profile
def DrawMsg(self, x1, y1, x2, y2, msg):

I thought above should be enough.
I guess I have to study the blog a bit better.
Your example seems quite different and I will try it.

Thanks, Pim

Maxime pointed me to Profiling Python Plugins.

However I have problems implementing it.
I added all the code: import cProfile, def profile(func), def PluginMessage(msg_type, data) and in the Area class

    @profile
    def DrawMsg(self, x1, y1, x2, y2, msg):

Now I get the console message:

    @profile
NameError: name 'profile' is not defined

Yes, I use the auto way.
I thought that using ScrollArea() it would only display that part (no need to draw the other parts).
So, fill the virtual UA once and then display parts of it using ScrollArea().

But if "you still need to draw completely the GeUserArea with all the DrawBitmap", there will be no speed benefit.

I will try it under R21 and will read "Profiling Python Plugins".

Thank you, Pim

So far I tried this, but no success.
In Command of the main dialog, I do the ScrollArea() call.
The 'visible' UA is 330x584. The actual (virtual) UA is larger in the y direction.

            self.area.ScrollArea(0,584, 0, 584, 330, 2*584)
            #self.area.Redraw()

Adding Redraw() dit not help.
I added no ScrollArea() in the Area class.

I am a bit confused about using ScrollArea() for my User Area (UA).
I want to display a lot of textures in my UA.

So, I created a UA with a scroll area and using the slider part of the textures are shown.
However, it is a bit slow, because the textures are all drawn using DrawBitmap() in DrawMsg().
I added SetClippingRegion(x1,y1,x2,y2), but that did not made things faster.

Reading the manual, I see that I can use ScrollArea(), only showing a part of the total UA.

Questions:

• do I use ScrollArea() in DrawMsg()
• do I still use DrawBitmap() to draw the textures?
• if not where do I draw all the textures, I later on display only a part using ScrollArea().

Could please provide some pseudo code or an example to show UA, DrawBitmap(), ScrollArea()?

Yes, strange.
But going from DiagnosticOutput() to GeConsoleOut() solved the issue.
Using maxon::String in DiagnosticOutput() seems to be the issue.
