Tree Control column widths

Mihai — Thu, 14 Oct 2021 00:48:24 GMT

Is there a way, other than html or CSS or whatever, to programmatically control the width of the columns in a tree control?

Or, at the very least, make them stay the way they were when the gviweb was last saved?

Hello Mihai, I ran into the same issue. There is no property that allows a user to control the column width. I created a simple project that only contained a tree control with 5 columns and a while loop. When the app runs the columns all seem to resize to some default value. I found a work around by modifying a section of "index.gviweb". There is a section called <TreeControl> in my example that started out as

I modified all of the <TabularControlColumn Id.......> sections to <TabularControlColumn Id...... "Width=[double]50"/> to set my column to 50 px wide. Saved and reloaded the project and now all of the columns are the size I want.

I suppose I should have posted here the solution I found, sorry to be so slack.

I found on GitHub Milan's web vi's experiments https://github.com/rajsite/webvi-experiments

I picked up from there a JavaScript which I incorporated in my application and now I can set my tree control's columns programmatically. It should work for everyone else.
