This Python script creates a simple whiteboard application with a graphical interface using the tkinter library. The application allows the user to draw lines on a virtual whiteboard, choose pen colors, import images and adjust line thickness with a slider. Here is a description of the main parts of the script:
The script starts by importing several tkinter libraries to create the graphical interface, manipulate colors, work with files, and perform other graphical tasks.
A main window is created using tk.Tk(), with a title ("WHITE BOARD"), fixed size and background color set.
. locate_xy(event): Records the mouse coordinates when the button is pressed.
. addline(event): Draws a line on the screen between the previously recorded coordinates and the current mouse coordinates.
. show_color(new_color): Updates the pen color.
. new_canvas(): Cleans the whiteboard, removing all drawings.
. insertimage(): Allows the user to select and insert an image into the whiteboard, which can be dragged.
. my_callback(event): Moves the inserted image to the mouse position when the right mouse button is pressed and dragged.
. Icons and buttons are added to the main window for functions such as clearing the whiteboard and importing images.
. A color palette is displayed in the left part of the window, allowing the user to choose the pen color.
. A canvas (Canvas) is created in the center of the main window, where the user can draw.
. Mouse events (click and drag) are linked to drawing functions.
The main loop (root.mainloop()) is started to run the GUI and wait for user interaction.
In summary, this script creates a simple whiteboard application with basic drawing features, image import, and control of drawing line color and thickness. It's a great base for building a more complex painting or note-taking application.
