Tkinter offers many built-in functions and methods that contain several utility functions to help us construct a user-friendly application. In tkinter, if you want to open a webpage, you can use the built-in Python library, webview, which allows the users to view the HTML content in its own native GUI window. You can install the webview library by using the following command −pip install pywebviewTo create a window that will open the requested HTML content, you have to first create a window container by using the create_window(win_title, 'URL') method and specify the URL in the method. This will create a ... Read More
In Tkinter, the toplevel widget is used to create a popup modal window. The popup window created by the toplevel window works similar to the default window of the tkinter application. It can have widgets such as text widget, button widget, canvas widget, frame, etc.The size and position of the toplevel window can be decided by making it flexible throughout the screen. In the toplevel window, all the widgets are always placed on top of the other windows.You can use root.winfo_x() and root.winfo_y() to get the position of the root window. Then, you can use the geometry method to position ... Read More
Tkinter provides many built-in widgets which can be used to create highlevel desktop applications. The LabelFrame widget is one of them, which allows the users to add a labelled frame. The Label is another widget in the LabelFrame, which is used to add text or images in a frame or any container.There are two main components of the LabelFrame widget, The Title Bar (also known as the text of the LabelFrame widget).The content (the content of the LabelFrame widget. You can add an image, or text as the content inside the LabelFrame widget.)To define a LabelFrame widget, you’ll need to ... Read More
APIs are extremely useful in implementing a service or feature in an application. APIs help to establish the connection between the server and a client, so whenever a client sends a request using one of the API methods to the server, the server responds with a status code (201 as a successful response) to the client.You can make a request to any API you want using one of the methods (GET, POST, PUT or DELETE). However, if you want to create an application where you need a request to the server using one of the publicly available API (for example, ... Read More
If we want to implement a text editor in an application that can accept multiline user input, then we can use the Tkinter Text widget. The Text widget in Tkinter is generally used to create a text editor for an application, where we can write text and perform operations like selecting, editing and creating a specific text in the application.If you want to highlight a text and provide a color to the highlighted text, then you can use the tag_add("start", "first", "second") method. The tag_add() method takes two arguments for selecting the specified text from the text widget. You can ... Read More
In Tkinter, you can set the GUI of the application by using a different geometry manager. The grid geometry manager is one of the most useful geometry managers in tkinter that is used to set the widgets location in the application using the 2D geometry form.With a grid geometry manager, you can set a certain number of rows and columns and place the widget in any location of the application. To set a certain number of rows and columns, you’ll need to specify the size value of the row and column configuration that helps to set the location of a ... Read More
To draw sine waves with SVG, use the following that closely approximates half of a sine wave. I have used a cubic-bezier approximation. Use the element.Example SVG HTML5 SVG Sine Waves Output
To draw SVG onto canvas, you need to use SVG image. Firstly, use the element which contains the HTML. After that, you need to draw the SVG image into the canvas.ExampleYou can try the following code to draw an SVG file on an HTML canvas SVG file on HTML Canvas var canvas = document.getElementById('myCanvas'); var ctx = canvas.getContext('2d'); var data = '' + ...

The HTML5 tag is used to draw graphics, animations, etc. using scripting. It is a new tag introduced in HTML5. The canvas element has a DOM method called getContext, which obtains rendering context and its drawing functions. This function takes one parameter, the type of context 2d.To draw a Bezier curve with HTML5 canvas, use the bezierCurveTo() method. The method adds the given point to the current path, connected to the previous one by a cubic Bezier curve with the given control points.You can try to run the following code to learn how to draw a Bezier curve on ...

To draw a Bezier curve, use the BezierCurveTo() method in HTML. Let us first see the syntax −ctx.bezierCurveTo(cp1x, cp1y, cp2x, cp2y, x, y);Here, cp1x − Represents the x-coordinate of the first Bezier control pointcp1y − Represents the y-coordinate of the first Bezier control pointcp2x − Represents the x-coordinate of the second Bezier control pointcp2y − Represents the y-coordinate of the second Bexier control pointx − Represents the x-coordinate of the ending pointy − Represents the y-coordinate of the ending pointFollowing is an example −Example HTML5 Canvas Tag var c = document.getElementById('newCanvas'); var ...
