Readme

Scrollable containers which just work!

If you have developed GUI applications, you probably know the pain of designing a clean front-end only to find that your application window is too large for your client's screen. Making the content scrollable is not straightforward (at least in Tkinter). Especially not after you have already written a lot of code to draw the content.

You can use ScrollableContainers to reduce headaches. It's available on PyPI!

pip install ScrollableContainers

Scrollable containers are currently available for the following GUI toolkits.

  • Tkinter
  • wxPython
  • PyQt5
  • PyQt6

This project is not sponsored or endorsed by, or connected with, any organisation or entity such as but not limited to: the Tcl Core Team, the Python Software Foundation, the wxWidgets Team, the wxPython Team, the Qt Company and Riverbank Computing.

Tkinter

ScrollableContainers.ScrollableFrameTk: a comprehensive implementation of a scrollable frame, and the flagship class of this project. (I wrote the other classes just for completeness.)

Usage

Add widgets to the frame attribute of a ScrollableFrameTk object. See examples.

Features

  • Handles resize events correctly.
  • Supports scrolling with the mouse wheel and touchpad.
    • Scrolling the mouse wheel or swiping vertically with two fingers on the touchpad triggers a vertical scroll.
    • Scrolling the mouse wheel while holding down Shift or swiping horizontally with two fingers on the touchpad triggers a horizontal scroll.
  • Horizontally centres the contents if the window is wider.

Notes

'<Button-4>', '<Button-5>' and '<MouseWheel>' are bound to all widgets using bind_all to handle mouse wheel scroll events. Do not unbind_all (or bind_all another function to) these three sequences!

wxPython

ScrollableContainers.ScrollablePanelWx: a thin wrapper around wx.lib.scrolledpanel.ScrolledPanel.

Usage

Add widgets to the panel attribute of a ScrollablePanelWx object. See examples.

Features

  • Does everything the wrapped class does.
  • Horizontally centres the contents if the window is wider.

PyQt5/PyQt6

ScrollableContainers.ScrollableAreaQt5/ScrollableContainers.Qt6.ScrollableAreaQt6: a thin wrapper around PyQt5.QtWidgets.QScrollArea/PyQt6.QtWidgets.QScrollArea.

Usage

Add widgets to the area attribute of a ScrollableAreaQt5/ScrollableAreaQt6 object. See examples.

Features

  • Does everything the wrapped class does.
  • Horizontally centres the contents if the window is wider.

In GTK, containers are widgets, so they can be aligned in other containers.

import gi; gi.require_version('Gtk', '3.0')
import gi.repository.Gtk as Gtk
import itertools

window = Gtk.Window()
window.connect('destroy', Gtk.main_quit)
window.set_default_size(256, 128)

scrolled_window = Gtk.ScrolledWindow()
window.add(scrolled_window)

grid = Gtk.Grid()
grid.set_halign(Gtk.Align.CENTER)
grid.set_row_spacing(20)
grid.set_column_spacing(20)
scrolled_window.add(grid)

dim = 10
for (i, j) in itertools.product(range(dim), repeat=2):
    label = Gtk.Label()
    label.set_label(f'Label\n({i}, {j})')
    grid.attach(label, j, i, 1, 1)

window.show_all()
Gtk.main()

Since horizontally centring the contents of a scrollable container is the primary function of this package, and GTK has built-in functionality to achieve the same, no submodule for PyGObject is implemented here.
