PYTHON TKINTER TREEVIEW FOCUS MANUAL

In my example I added an entry so that you can compare the look on the two widgets.

In addition, I also deactivated the possibility to open/close items when the Treeview is disabled using binding tricks on the mouse click. If you have a bunch of related variables, make that obvious by putting them all in a list, class MyWindow(tk.Tk): nbro is right, you need to change the Treeview style to make it look disabled. Add the following after calling focusset (): tree.focus ('gallery1') Share. You've done the first two but not the third.

In the example below I use StringVars to set values in the Entry widgets. You need to make sure the widget as a whole has focus, that an item is selected, and the selected item needs to have the focus. Have you run across tkinter variables? I think they are much easier to use than directly working with widgets. Thanks again Yoriz for pointing me in the right direction. Treeview widgets are created using the ttk.Treeview class: tree ttk.Treeview ( parent) Treeview widgets are created using the ttk::treeview command: ttk::treeview. remember to pass the event 'e'(or whatever you want to name it) this is the only thing that caught me up As with most Tk widgets, it offers incredible flexibility so it can be customized to suit a wide range of situations. # set the values from the list into the e1-e6 text boxes. call item function and throw values into a list. Self.e6.delete(0, 'end') # call the clear-entry function, then use focus method to select which item in the tree. ('', lect_record) #clears all text boxes (e1-e6 are textbox items) #bind single click event to treeview and call function that sets values. If anyone searches this, here is what I did. Note that selection get does not retrieve the selection in the UTF8_STRING format unless told to.Ok, this ended up being a lot easier than I thought it would be. If the selection is returned in a non-string format, such as INTEGER or ATOM, the selection command converts it to string format as a collection of fields separated by spaces: atoms are converted to their textual names, and anything else is converted to hexadecimal integers. (this format is different than the selection type see the ICCCM for all the confusing details). The selection owner may choose to return the selection in any of several different representation formats, such as STRING, UTF8_STRING, ATOM, INTEGER, etc.

Type specifies the form in which the selection is to be returned (the desired “target” for conversion, in ICCCM terminology), and should be an atom name such as STRING or FILE_NAME see the Inter-Client Communication Conventions Manual for complete details. Selection defaults to PRIMARY and window defaults to “.”. Retrieves the value of selection from window's display and returns it as a result. To create a Treeview widget, you use the ttk.Treeview class: tree ttk. Return self.tk.call(('selection', 'get') + self._options(kw))It does not look like this is meant to be used in programs.įrom the documentation for tk: Wrote:selection get ?-displayof window?-selection selection?-type type? A Treeview widget allows you to display data in both tabular and hierarchical structures. Return self.tk.call(('selection', 'get') + self._options(kw)) If 'type' not in kw and self._windowingsystem = 'x11': A keyword parameter type specifies the form of data to beįetched, defaulting to STRING except on X11, where UTF8_STRING is tried Parameter displayof specifies a widget on the display Found a solution at last - seems that Treeview widget need to be set focus two times: first for the widget itself, and second for an item: lectionset ( items 0 ) list.focusset () list.focus ( items 0 ) this fixes a problem. '''Return the contents of the current X selection.Ī keyword parameter selection specifies the name of From the code: Lib/tkinter/_init_.py Wrote: def selection_get(self, **kw): ee = ttk.Treeview(parent, columns=columns, show='headings', selectmode='browse')ĭata.append((f'Column 1 Data ') For that, I found a tkk.Entry derived class, to which I made a few adaptations to suit my needs (it may also be that who wrote it. In order to edit the elements of a ttk.Treeview I searched to have a ttk.Entry and a ttk.ComboBox poping up from the treeview whenever the user double clicks on it.

If you are wanting to get the values of selected row, maybe this will help get you started.
