Specifies the mouse cursor to be used for the widget. If set to the empty string the defaultthe cursor is inherited for the parent widget.
Determines whether the window accepts the focus during keyboard traversal. If 0 is returned, it means that the window should be skipped entirely during keyboard traversal.Within a given theme, every widget has a default widget class ; we use this term to distinguish ttk classes from Python classes.
Each widget also has a style. The default style for a widget is determined by its widget class, but you may specify a different style. In ttkwidget classes and styles are specified as strings. In all but one case, the default style name of a widget is 'T' prefixed to the widget name; for example, the default button widget class is 'TButton'.
There are some exceptions:. Style names for ttk widget classes. At runtime, you can retrieve a widget's widget class by calling its. The built-in styles are all a single word: 'TFrame' or 'TRadiobutton'for example. To create a new style derived from one of the built-in styles, use a style name of the form ' newName. For example, to create a new style of Entry widget to hold a date, you might call it 'Date. Every style has a corresponding set of options that define its appearance. For example, buttons have a foreground option that changes the color of the button's text.
To change the appearance of a style, use its. The first argument of this method is the name of the style you want to configure, followed by keyword arguments specifying the option names and values you want to change. For example, to make all your buttons use green text, where s is in instance of the ttk.

All the ttk Widgets accepts the following options:. The following options are supported by widgets that are controlled by a scrollbar.
Usually this option consists of the method Scrollbar. This will cause the scrollbar to be updated whenever the view in the window changes.
The following options are supported by labels, buttons and other button-like widgets. Specifies how to display the image relative to the text, in the case both text and images options are present. Valid values are:. A state specification is a sequence of state names, optionally prefixed with an exclamation point indicating that the bit is off.
I haven't found any mention of this in tkdocs or other documents. After long research I haven't found such feature so I guess there's any. Tk is very simple interface, which allows programmer to build 'high-level' features from the basics. So my desired behaviour this way. You could also pop up a tool window with the editable fields listed with Entries to update the values. This example has a treeview with three columns, and does not use subclasses.
This gets bound to a routine with the bind method, then you use the selection method to get the ids of the items selected.
This is just for creating a tree for the specified path that is set in the constructor. The event function is left in a way that the item could be used in many ways. In this case, it will show the name of the item when double clicked on it.

Treeview widget is to present a hierarchical structure so that the user can use mouse actions to reveal or hide any part of the structure. Strictly speaking, the hierarchy shown in a Treeview widget is a forest: there is no one root, just a collection of top-level nodeseach of which may contain second-level nodes, each of which may contain third-level nodes, and so on.
You may have encountered this particular presentation as a way of browsing a directory or folder hierarchy. The entire hierarchy is displayed like an indented outline, where each directory is on a separate line, and the subdirectories of each directory are displayed underneath that line, indented:.
The user can click on the icon for a directory to collapse close it, hiding all of the items in it. They can also click again on the icon to expand open it, so that the items in the directory or folder are shown. The Treeview widget generalizes this concept so that you can use it to display any hierarchical structure, and the reader can collapse or expand subtrees of this structure with the mouse.
One of the entities being displayed in the widget. For a file browser, an item might be either a directory or a file. Each item is associated with a textual label, and may also be associated with an image. Every item in the tree has a unique identifier string called the iid. You can supply the iid values yourself, or you can let ttk generate them.
Tk - Treeview Widget
The items directly below a given item in a hierarchy. A directory, for example, may have two kinds of children: files and subdirectories. For a given item, if it is at the top of the hierarchy it is said to have no parent; if it is not at the top level, the parent is the item that contains it. The ancestors of an item include its parent, its parent's parent, and so on up to the top level of the tree.
Top-level items are always visible. Otherwise, an item is visible only if all its ancestors are expanded. The descendants of an item include its children, its childrens' children, and so on. Another way of saying this is that the subtree of an item includes all its descendants. Your program can associate one or more tag strings with each item. You can use these tags to control the appearance of an item.
For example, you could tag directories with the tag 'd' and files with the tag 'f'and then specify that items with tag 'd' use a boldface font.
You may also associate events with tags, so that certain events will cause certain handlers to be called for all items that have that tag. For example, you could set up a file browser so that when a user clicks on a directory, the browser updated its contents to reflect the current file structure. Your Treeview widget will be structured with multiple columns. The first column, which we'll call the icon columndisplays the icons that collapse or expand items. In the remaining columns, you may display whatever information you like.
For example, a simple file browser widget might use two columns, with the directory icons in the first column and the directory or file name in the second columns. Or you might wish to display file sizes, permissions, and other related data in additional columns. The operations of the Treeview widget even allow you to use it as a tree editor.
Your program can remove an entire subtree from its location in the main tree and then attach it later at an entirely different point.
You are not deleting the whole tree you are just deleting all children from the root item, because you use delete for each item in your iteration. With the. We need to get the values associated with the selected item which is what the tree1.Python-GTK 02-06: Treeview
