In this article we will see how we can trigger on mouse drag event in PYGLET module in python. Pyglet is easy to use but powerful library for developing visually rich GUI applications like games, multimedia etc. A window is a “heavyweight” object occupying operating system resources. Windows may appear as floating regions or can be set to fill an entire screen (fullscreen). The mouse was moved with one or more mouse buttons pressed. This event will continue to be fired even if the mouse leaves the window, so long as the drag buttons are continuously held down.
We can create a window with the help of command given below
pyglet.window.Window(width, height, title)
Below is the syntax of the on mouse drag event, this method get called when this event is triggered
@window.event
def on_mouse_drag(x, y, dx, dy, buttons, modifiers):
print("Mouse is dragged")
Below is the implementation
Python3
# importing pyglet moduleimport pygletimport pyglet.window.key# width of windowwidth = 500# height of windowheight = 500# caption i.e title of the windowtitle = "Geeksforneveropen"# creating a windowwindow = pyglet.window.Window(width, height, title)# text text = "neveropen"# creating a label with font = times roman# font size = 36# aligning it to the centrelabel = pyglet.text.Label(text, font_name ='Times New Roman', font_size = 36, x = window.width//2, y = window.height//2, anchor_x ='center', anchor_y ='center')new_label = pyglet.text.Label(text, font_name ='Times New Roman', font_size = 10, x = 25, y = 25)# on draw event@window.eventdef on_draw(): # clearing the window window.clear() # drawing the label on the window label.draw() # key press event @window.eventdef on_key_press(symbol, modifier): # key "C" get press if symbol == pyglet.window.key.C: print("Key C is pressed")# on mouse drag event@window.eventdef on_mouse_drag(x, y, dx, dy, buttons, modifiers): # printing some message print("Mouse is dragged") # image for iconimg = image = pyglet.resource.image("logo.png")# setting image as iconwindow.set_icon(img) # start running the applicationpyglet.app.run() |
Output :
Mouse is dragged Mouse is dragged Mouse is dragged Mouse is dragged Mouse is dragged Mouse is dragged Mouse is dragged Mouse is dragged Mouse is dragged Mouse is dragged Mouse is dragged Mouse is dragged Mouse is dragged Mouse is dragged
