If you are planning to create an application whether it’s a big project or just a small yet functional app for desktop or mobile, the first thing you must learn, and master, is how to create a smooth and neat Graphical User Interface (GUI). In order for users to interact with your app, you need to build an interactive GUI. If you are using Python Programming language, it is always ideal to…
Python is a high-level and general-purpose programming language that has been widely used by programmers in many different fields. From a recent PyCon, we have learned that the Python programming language has been effectively applied in Agriculture, High Energy Physics, and…
Do you want to be able to make your Python apps play sounds and music? Whether it’s Linux, macOS or app development on Windows, adding sounds or the ability to play music adds a great new dimension to your programs and lifts them free of being restricted to the beeps…
One of the key user interface paradigms when you develop Windows software is the ability for users to interact with objects on the screen with their mouse. Most often this means being able to click things but over time the concept of being able to drag – and drop – items has become a common capability. It enables users to be able to do things like reorder lists, add items to selections…
In this tutorial (which doesn’t just apply to Windows development) you will be learning how to only pad one side of a widget at a time instead of the default two sides. Whenever we pad widgets, we use pady and padx, but by default we put padding on two sides of the…
DelphiVCL is a powerful framework for creating excellent, modern, graphical user interfaces (GUIs) for your Python programs. DelphiVCL is independent of Delphi and does not require Delphi to be installed. However, you can make use of Delphi’s powerful IDE software and its…
There are various tools for writing, developing and running Python code, from interactive mode to full-featured IDE software such as PyScripter and the excellent RAD Studio. In this article I will give a complete overview introduction of the tools that I have used myself to write great Python apps over the years.
What is the simplest way to run Python code?
The quickest way to run Python…
When it comes to Graphical User Interface or GUI Programming in Python, Tkinter is a default toolkit or default library available for users, especially for beginners to build some robust small-scale applications in Python. While there are many other options available but…
We use the Value property to set or specify any actions or parameters in the DelphiVCL library while using the IDE software.
Here is the working example of Value with CanSelect parameter:
def grdTestSelectCell(Sender, Col, Row, CanSelect):
if Col == 2 and Row ==…
The Lines Property contains the individual lines of text in the memo control. This works for native Windows development.
We use Lines to manipulate text in a memo control on a line-by-line basis. Lines is a DelphiVCL.Strings or TStrings object, so the TStrings methods may be used for Lines to perform manipulations such as counting the lines of text, adding new lines, deleting lines, or…
