Examples

• Buttons
• Data binding
• Drawing
  • Simple paint
• Fonts
• Listbox
• Menubar
• Misc
• Persistence
• Plots
• Sizing
• Spacing
• Tables
• Threading
  • Progress bar
• Window

Buttons

Examples of how to implement various types of buttons. This includes how to implement a button which changes colour when clicked and how to implement nested radio buttons.

Data binding

Examples of how to link a data structure to GUI items so that changes made using the GUI are reflected in the underlying data structure.

Drawing

Examples of how to use the drawing API.

Simple paint

A very simple implementation of a paint app. It demonstrates how you can click and drag the mouse on a dpg.add_drawlist and draw basic free-form lines using dpg.draw_line.

Fonts

Examples of how to use custom fonts. And some tips on how to get the best results.

Listbox

Examples of custom listbox widgets which extend the functionality of the default listbox. Includes how to implement a listbox which is unselected by default and how to respond to key presses.

Menubar

Examples of how to implement all the different types of menubar and how to implement a right-aligned menubar.

Misc

Miscellaneous examples.

Persistence

Examples of how to save and load the state of a GUI. This includes the values of GUI items, the position of windows, etc. A simple example using dict is shown as well as an approach using dataclasses. Both store the app state in a JSON file.

Plots

Examples of how to implement various features in plots. Such as enforcing axes limits and updating colours and marker styles.

Sizing

Examples of how to size/re-size GUI items. There are some quirks with sizing - mainly to do with getting the correct size of an item on startup.

Spacing

Examples of how to space GUI items using different methods. This includes automatic spacing, spacing using a grid of child windows and spacing using tables.

Tables

Examples of how to use tables.

Threading

Examples of how to use threading in DearPyGui. Includes a start/stop button which can be used to start/stop a thread and a progress bar to show the progress of a task.

Progress bar

A basic progress bar with a start button. Once running, the start button changes to a pause button. The task can then be paused, upon which the pause button changes to a resume button and a reset button appears.

Window

Examples of how to manage windows. This includes how to create a window which is always on top and how to drag the viewport when decorated=False. Also includes restricting the position of a window and how to implement a clicked handler for child windows.

Thank you for your example

Thank you for your example

Let me learn a lot of knowledge

Do you consider the Node Editor example

Do you consider the Node Editor example
There are too few official tutorials
