# The parameter pos is a pixel coordinate, which needs to be converted into a scale coordinate # After capturing the click event, the actions to be done are completed in the mouseover function, mainly extracting the coordinates of the points The main codes of mouse movement are as follows: # Capture mouse movement events So in the whole program, I used two trigger events, one is mouse click and the other is mouse movement. After testing, the coordinates extracted by moving the mouse event are accurate. Normally, the return value of sigMouseClicked is an event, which contains the coordinates of the click time, but this coordinate is inaccurate, which is somewhat different from the actual position.

X y mouse coordinates code#
The main code is as follows: # Capture mouse click events In practice, I also divide this part into two steps: a) capture the mouse click signal.
I haven't used pyqt before, so I don't know how to capture the mouse click signal, let alone extract the corresponding position coordinates. (self.updateData)ģ) Left click the drawing interface to add a new point. # Start the timer and notify to refresh the data every 100ms When you are finished, click cancel on the confirmation dialog. If you want to continue collection of points, press Ok on the confirmation dialog and click again. Clicking once alerts the ordinates to your screen. # Give the X and Y coordinates of points and draw a scatter diagramĢ) After the number of nodes or coordinates change, the position can be updated in real time. This will give you the x and y coordinates of a point on your screen. Self.scatter = .plot(pen=None, symbol='o') My requirements are mainly divided into the following parts: 1) Given the node coordinates, it can be displayed in the form of scatter diagram. I learned from the online code, combined with my own needs, and finally realized the functions I needed. After a search, I found that pyqt seemed to meet my needs, and I could find some relevant code. It feels that matplotlib completely depends on data-driven (that is, it can draw pictures by providing data), but it can not realize the two-way interaction between users and graphics (that is, users can generate new points by clicking with the mouse). However, it seems that it can not achieve the functions I need. Its user interface is highly minimalistic.
X y mouse coordinates portable#
In ordinary python drawing, my commonly used tool is matplotlib. As a conclusion, Mouse Locator is a simple, portable application that can help you determine your mouse cursors on-screen X and Y coordinates with ease. In a recent project, the required function is to use the mouse to add nodes (the position where the mouse clicks is the node coordinates), and the point coordinates can be displayed visually and dynamically after being added. and this in your Picturebox MouseMove event: LocalMousePosition PictureBox1.PointToClient (Cursor.Position) TextBox2.Text ('X' & LocalMousePosition.X & ',' & 'Y ' & LocalMousePosition.Y) This will give you the correct position within your Image. Widget_x2, widget_y2 = my_text.1) Problem motivation and usage scenarios Widget_x1, widget_y1 = my_button.winfo_rootx(), #Get the coordinates of both text widget and button widget #Update the coordinates with respect to the tkinter frame My_text= Text(win, height = 5, width = 52) We will use winfo_rootx() and winfo_rooty() functions which return the actual coordinates of the widget with respect to the frame or window. Now, to get the actual coordinates of the widget, we can use the geometry methods available in the tkinter’s library. Let us suppose that we have created a text label widget which is having some position in the tkinter frame. Widget and its coordinates on the tkinter frame using other functions and libraries. Including buttons, text boxes and labels. For building GUI applications it provides some widgets
It has many toolkits andįunctions or modules available which can be used to define the different attributes Tkinter is widely used to create GUI based applications.
