Operating System: Windows 2000 Pro

I have several problems with gobjects. On the picture below I want to get the lower gobject with labtalk commands.

[img]http://www.originlab.com/ftp/forum_and_kbase/Images/gobjects.jpg[/img]

1 I want to set the color of the gobject to transparent:
[code]gobjectname.fillcolor =0;
or
gobjectname.fillcolor =color(none);[/code]

As you can see on the upper gobject it is actually set as transparent when I check this with the gui, but it shows as black. If I set it with the gui it works.

2 I want to remove (set to 0 width) the border/frame (Rahmen Tab) lines of the gobjects. The ones that are in red on the upper gobject.
I tried gobjectname.lineWidth=0; and gobjectname.lineType=0;, but I get this error: object property not found!

3 I want to set the fill pattern (which with the gui works).
I have done that for a layer with the set command like: set datasetname/worksheetname -pfp 1;. This did not work form for gobject, because gobject is other data type.

greg	Posted - 12/14/2010 : 10:20:15 AM Watching the tree in debug revealed that -4 is the transparent color code. After a few tests, I found that this works: rect.fillcolor = 2^32 - 4; Most graphic objects have only limited LabTalk access, so use rdremov's code as an example of working around that problem.
asenv	Posted - 10/14/2010 : 06:49:30 AM Thank you very much, the function does its job prefectly well. Just for the other people that read the topic I will say that in labtalk I load the function with run.LoadOC("path_to_.c_file",2); and execute the functions inside the .c file just with writing the function name - somefunction;
rdremov	Posted - 10/13/2010 : 4:52:23 PM Here is OC functin which should do the job: void change_rect_fill(string strName = "Rect") { GraphLayer gl = Project.ActiveLayer(); GraphObject go = gl.GraphObjects(strName); Tree tr; tr.Root.Border.Width.dVal = 0; // no border tr.Root.Fill.Color.nVal = INDEX_COLOR_TRANSPARENT; // no fill color tr.Root.Fill.Pattern.Style.nVal = 3; // sparse diagonal tr.Root.Fill.Pattern.Width.dVal = 1; // pattern width tr.Root.Fill.Pattern.PatternColor.nVal = 0; // black pattern color int err = go.UpdateThemeIDs(tr.Root, "Error", "Unknown tag"); go.ApplyFormat(tr, true, true); } It is based on theme properties access.
