Introduction

Recently, I always develop mobile App by Flutter. In the process of my development, I found that gradient rendering components can make the interface look better.

So I start to think, how do I do it in desktop application development by PyQt5?

Introduction

Recently, because I have been studying the interface of the program, I got many strange problems.

I want to record today is how to merge two pictures. I found that if I simply use the composite() function in PIL, the second picture will be overwritten by the first picture. So, I started to try convert the background of the second picture to transparent.

After converting the image to a transparent background, the result of the merging is quite natural to me.

I will start to introduce how to merge two pictures in below.

Introduction

When we using PyQt5 framework to develop a GUI program, we usually need some icon to display our buttons or components. Many times we can load pictures from outside, but if we need common icons, such as play icon, close icon, minimum icon ... etc, we can use the built-in icon picture from QStyle module.

This has another advantage: we don't have to worry about pictures when packing the GUI program.

Below I will introduce how to use the icons in QStyle.

Recently, the GUI I'm developing is often in a state of cessation. I think maybe I need "QThread" to help me. But when I learning how to use QThread, I was surprised to find one thing.

The tutorial in internet, it show me the LCD component is very slow, I need to use QThread to solve it ......

Introduction

If we finished a program in Python, and we want to share it for our friends their computer have no Python (Maybe they won't to install it.), we can use "PyInstaller" to convert our program to be a exe file.

I recently started to want to make a more beautiful interface. So I think I can't place the components casually as before.

Thanks to this, I want to record two very important processing methods today - "How to hide components, show components", "How to make components automatically fit to window size".
