treeview

问题 Im setting up a new Form and Im having some issuis with the TreeViewNodes checking and uncheking the childs. Its easier to see the problem in this short clip Normally it works properly but sometimes it gets stuck (I think there is a conflict with selection but Im not sure) and the methods arent applied properly. I have this methods to check and uncheck the childs: private void Treeview_AfterCheck(object sender, TreeViewEventArgs e) { if (e.Action != TreeViewAction.Unknown) if (e.Node.Checked)

问题 is there any way I could modify the the tkinter treeview item tag? I know how to create item with tag with insert command, but when I: tree.set(tree.selection()[0],0,'some text in red', tags='red') I get TypeError: set() got an unexpected keyword argument 'tags' The ultimate goal is to change row or column colors... Thanks! 回答1: The documentation on Treeview (here for instance) says that there is a method called item that can be used to set or retrieve the options of a tree item. tree.item

问题 This is my first post, please excuse me if I made mistake in the format, I will gladly change it if required. I'm creating an interface for scientific datas analysis using Tkinter. For a list of molecules, four can be represented in separate plots. On the side, I use a Treeview to show some numbers about all molecules. (not just the displayed ones) When a treeview row is about a displayed plot, i want that row's text to be the same color. For each displayed graph, I place a different tag on

问题 I want to keep my parent folder names uncheckable. but i can not pass the option with individual node here. I wrote code like this. $("#treeview-checkable").treeview({ data: root.attributeTopicList, showIcon: true, showCheckbox: true, showBorder: false, showTags: true, }); }; 回答1: I had to Add some lines in bootstrapp-treeview.js file Process-->> Go inside bootstrapp_treeview.js See how its render function works You will find that after treeview fire any event or make any changes on DOM it

问题 I'm using sizetree() function from plotrix package to draw my data structure as a tree ( see below ) and it works just fine. However, I was wondering if there might be another way (or a package) that would provide a more elegant tree plot of the same data with the same information displayed? ( Note: In the below plot, fonts are unnecessarily either too big or too small so are the rectangles etc. also may be the plot could be inverted to get a better look.)-- it's subjective but I appreciate

问题 Does anyone know how I can align the collapse/expand images with the center of my icon? Using a white theme they are correct, but in the dark theme, the arrows seem to be bottom-aligned: 回答1: If you're using VCL Style Utils components, then modify UxTheme_TreeView in Vcl.Styles.UxTheme.pas case iPartId of TVP_GLYPH: begin LColor := StyleServices.GetSystemColor(clWindowText); LRect := pRect; LRect.Top := LRect.Top + 1; // <---- here's the change //LRect.Top := LRect.Top + 5; LRect.Left :=
