7 months ago Hello @wyzarddoc72 thanks for trying pygubu, and sorry for the late response.
The bindings panel
The purpose of this panel is to speed up the definition of bindings in the designer. To do this, the user must define three parameters:
Sequence descriptor: sequence or event to be associated with
Event handler: is the name of the function or method that will be called when the event is fired.
Add: Specifies that the handler will be added to the handler list associated with the same sequence or event.
Example
The ttk.Treeview widget raises a virtual event "\<\<TreeviewSelect>>" when the user selects a row from the treeview. To define in the designer a function that reacts when this event is executed, proceed as follows:
- Select a treeview in the designer
- Navigate to the Bindings tab
- In "Sequence Descriptor", write or select \<\<TreeviewSelect>>
- In "Event Handler", enter the name of the method. In this example "on_row_selected"
- Leave "Add" blank
If we generate the code with the "Application" template it will look similar to the following:
class BindingsApp:
def __init__(self, master=None):
self.builder = builder = pygubu.Builder()
builder.add_resource_path(PROJECT_PATH)
builder.add_from_file(PROJECT_UI)
# Main widget
self.mainwindow: tk.Toplevel = builder.get_object("toplevel1", master)
builder.connect_callbacks(self)
def run(self):
self.mainwindow.mainloop()
def on_row_selected(self, event=None):
passThe call to "builder.connect_callbacks(self)" connects the bindings to the generated methods.
In the generated "on_row_selected" method we write the code necessary to react to that event.
For more info about bingings see this page I hope this information helps you.

*I have looked for information on how to use the bind options in the designer and have had no luck. Any help would be appreciated. Request --> A button or fill in the blank for text boxes so string text input could be done with less frustration thanks for all your hard work other than a few glitches the program works great.
