Within a node the items are indexed: 0 being the first item, 'end' representing the position after the last item. The parent node is '' and is not displayed. There are three ways of adding images on Python Tkinter. The items are organized in the form of a tree. However, that turns out to be a handy workaround for the Stack Overflow user who ran into this problem, so maybe it's better not to change that. A treeview widget can display a hierarchy of items. It's just that ttk._val_or_dict doesn't call _tclobj_to_py on the value when it gets back a key-value pair, and I don't see why it shouldn't. self.img PhotoImage(file'resourcesinformationpicto.gif'), end, textInformationpicto.gif, openTrue, imageself. The tuple ('180518-23', '23/06/18') is no more or less conversion-worthy than the same tuple inside the list (, '',, '',, ('180518-23', '23/06/18'),, 0,, ''). You can display your image using the image argument in the w.insert method. But looking into what tkinter is getting back from Tcl, there's really no difference here. Specifies how the heading text should be aligned. The treeview widget can show an image in the first column, for each row. Maeanwhile, if you instead call em(row, options='values'), the string is left alone.Īt first glance, that made sense. Specifies an image to display to the right of the column heading. ttk.Treeview Insert a row with a PNG image. But it does, because ttk._tclobj_to_py just does a try: return int(s). If you store the int 123_456, Tcl of course gives you back '123456', not '123_456', so there's no reason for tkinter to convert '123_456' to an int. However, I think it should only be converting strings that could be a valid Tcl int. This seems reasonable, because it's legal to store an int in a TreeView, and if tkinter didn't convert the values, you'd store 123 and get back '123'. If you store a string that looks like an int in a TreeView's values, then call em(row), the dict's 'values' value has that string converted to an int. See this StackOverflow question for a repro case: Has anyone any experience using Tkinter for TMLs? I´ve tried many ways for several times in the last weeks but unfortunately with no (and maybe other functions) is overzealous in converting item values to intsĬreated on 04:49 by abarnert, last changed 14:59 by admin. Items.Add(XXX) or Items.GetItemAt(Y) etc. I already have some simple TreeView on my macros but would like to extend them and I don´t find the way with simple properties, etc such us. The purpose of the ttk. When we have a relation between data in that case we have Treeview. I´ve been struggling to get proper TreeViews on my macros and therefore was looking for alternatives and Tkinter sounds like a great module supporting a lot of things but especially what I need for TreeViews on my macros. Tkinter Treeview refers to hierarchical representation. Images can be in a variety of formats including jpeg images. Here is how you add item to TreeView: mytreeViewItem=TreeViewItem()myTreeViewItem.Header="Something"MyTreeView.Add(mytreeViewItem)Īnd I guess it looks better than external here's the example: Here is the sample code for TreeView in IronPython It's far richer and there's no need for an external reference. NET Framework TreeView instead of third party. Subject: Tkinter and TreeView - Any experience with Tkinter?
