Re: Close nodes in Tree View widget
Thank you! https://quality.livecode.com/show_bug.cgi?id=21361 --Andrew Bell Quoting Brian Milby : Could you open a bug report/enhancement request for this? I’ll see what I can do about a PR targeting 9.1 release. I can think of several ways to address the situation. Easiest would be to reset the array that handles what is expanded when the data array is changed. Would not be hard to add a separate handler to collapse all nodes. Once done, you could pull the updated source and compile/use locally until it makes it into a release.

In fact, if you set the hilitedElement to a node that isn't open it will hilite the next node that is open instead. (bug?) This isn't critical for this project as it is just an internal tool that only I use, but the only workaround I could come up with is to delete the widget and then create the widget again via script along with all the attributes. --Andrew Bell > Date: Wed, 13 Jun 2018 23:02:52 +0100 > From: Alex Tweedly > Subject: Re: Close nodes in Tree View widget > > I can't try it out right now - but would it be any good to set the > arraydata to empty, and then load the new values you want ?

Re: Close nodes in Tree View widget
Setting the arrayData to EMPTY acts the same as setting the arrayData to some other array: the open nodes remain open. I even tried changing the number of elements in the array to something as low as 1 but it still remembered what nodes had been open when setting the arrayData to something with more elements. There are no properties in the dictionary that describe this type of operation. The closest I could find was hilitedElement but that doesn't actually open or close a node leaf.

Re: Close nodes in Tree View widget
I can't try it out right now - but would it be any good to set the arraydata to empty, and then load the new values you want ? That might (effectively) delete and recreate the relevant nodes, and thereby reset the status of the leaf nodes. Alex.

Close nodes in Tree View widget
I'm working with the Tree View widget and have found that leaf nodes stay open even after the arrayData has changed. For example, if I click on leaf node 2 and 4 to open them up for further inspection but then load new arrayData those same leaf nodes are already expanded with the new data. Is there a way via code to close all the leaf nodes, or to restrict the widget so only 1 node can be open at a time? --Andrew Bell ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
