![]() ![]() Name ] Name is the name of a cursor in the standard X cursor cursor, Is returned and an error message will be stored in interp's result Such as when objPtr refers to a non-existent file, then None If an error occurs in creating the cursor, Information about the return value in objPtr, which speeds upįuture calls to procedures such as Tk_AllocCursorFromObj and ![]() It re-uses an existing cursor if possible andĬreates a new one otherwise. Tk_AllocCursorFromObj takes as argument an object describing aĬursor, and returns an opaque Tk identifier for a cursor corresponding Re-used efficiently, thereby avoiding server overhead, and alsoĪllow cursors to be named with character strings. These procedures manage a collection of cursorsīeing used by an application. Have been returned by some previous call to Tk_GetCursor or Textual description of background color for cursor. Textual description of foreground color for cursor. Same as objPtr except description of cursor is passed as a string andĭata for cursor cursor, in standard cursor format.ĭata for mask cursor, in standard cursor format. Modified to cache pointer to corresponding Tk_Cursor. Token for window in which the cursor will be used.ĭescription of cursor see below for possible values. Tk_GetCursorFromData( interp, tkwin, source, mask, width, height, xHot, yHot, fg, bg ) Tk_AllocCursorFromObj( interp, tkwin, objPtr ) Tk_AllocCursorFromObj, Tk_GetCursor, Tk_GetCursorFromObj, Tk_GetCursorFromData, Tk_NameOfCursor, Tk_FreeCursorFromObj, Tk_FreeCursor - maintain database of cursors (Not dragging by the way, since that ends with a event).Tk Library Procedures - Tk_AllocCursorFromObj manual page NAME Tk_AllocCursorFromObj, Tk_GetCursor, Tk_GetCursorFromObj, Tk_GetCursorFromData, Tk_NameOfCursor, Tk_FreeCursorFromObj, Tk_FreeCursor - maintain database of cursors SYNOPSIS ARGUMENTS DESCRIPTION name ] sourceName maskName fgColor bgColor sourceName fgColor sourceName BUGS KEYWORDS This way you bind your callback to a tag that is handled after all those actions mentioned in the quote above, so you will see the cursor to be at position 0.ĭo keep in mind that this affects all clicks, including double click, triple click, control-click. To do this you can add a bindtag after the class and bind to that: e.bindtags(((str(e)), "TEntry", "post-click", ".", "all")) However, you can add an event after the default event has been handled. ![]() Because this is the order in which the events are handled, you never see the cursor at location 0. So even though you did put the cursor at position 0, the default Entry event for the mouse button is to change the location of the cursor to where you clicked. Dragging with mouse button 1 strokes out a selection between the insertion cursor and the character under the mouse. The default event from the ttk Entry inherits from the standard Tkinter Entry which, according to the manual, isĬlicking mouse button 1 positions the insertion cursor just before the character underneath the mouse cursor, sets the input focus to this widget, and clears any selection in the widget. When you click the widget, first your on_click function is called which puts the cursor at the start, then the default event for a ttk Entry box is called. Now, when you do e.bind("", on_click), you bind the on_click function to the widget e. is the widget's Toplevel or Tk instance and all is a tag that can be bound to that all widgets have. !entry is the current widget e, TEntry is the ttk Entry class. To see what these are you can print(e.bindtags()) which prints ('.!entry', 'TEntry', '.', 'all') This is due to the order in which events are handled in Tkinter.įor a detailed explanation read this answer, but in short events are handled in the order of the bindtags.
