You will not find many examples covering the Graphics View Framework on the Internet.
Or in any other material. I had only 2 working examples, when I began studying the framework. This chapter has 11 code examples, ranging from a simple starting example to a skeleton of a computer game.
Here you will learn about transformations, selections, item animations, zooming, collision detection or grouping of items. Layout management is considered to be one of the most difficult areas of GUI programming.
Writers usually only skim the topic, covering the very basics of it. Based on my experience while writing a complete e-book dedicated to layout management, this chapter was a piece of cake.

Once you know the principles behind the process, you can utilize them in other GUI toolkits too. With almost 40 pages and 17 examples, you will learn everything important about layout management.
In the third chapter, we will show how to create three custom widgets: This is another area on which you will find very little information elsewhere.
In the QtSql module chapter, we will cover the basics of the QtSql which is used for database programming. Network programming is covered in the networking chapter. The examples show how to download an icon from a web page, connect to an FTP server, create a simple web server or determine weather conditions.
One of the best ways to learn programming is to create computer games. As a bonus, you will have three simple 2D games: Nibbles, Sokoban, and Minesweeper.
Home Advanced PyQt4 tutorial The e-book has pages. QWidget Next, we define our window.
Now this can sometimes be a little confusing. With GUIs, you generally have what is referred to as the "application," or the "frame," and then you have the "window" or the actual "gui" part. The frame is just the encapsulation of the window, literally on the screen, as well as in the background.
You will probably better understand this as time goes on, but think of "application" as literally the border that goes around your window. Keep in mind, that applications and their windows are created in memory first, then they are brought to the user's screen last.
This is the same process that you see done with other forms of Graphics in programming, like games with PyGame, or graphing with Matplotlib. The reason for this is graphical rendering is cumbersome, and it would be rather inefficient to continuously be making edits and refreshing to the user's screen for each element.
So, when we modify the window like this, it is not like the window will pop up full screen, and then change shape moments later. The screen has not yet been shown to the user, we're just building it in the memory.
What is PyQt Multiple Document Interface?
QWidget class. It is taking four parameters from us.
First you have the window's starting x coordinate, then you have the starting y coordinate 0 and 0. Next, you have the window's dimensions, which are and , meaning pixels wide and tall.They are converted to string to concatenate the caption of each push button to be added at ith row and jth column.

The widgets in a QSplitter object are laid horizontally by default although the orientation can be changed to Qt. It is linked with the currently selected index of QListWidget.
QLineEdit On the flip side, it is not always clear what the hell is going on, or what you're supposed to do about it. The top level window has three buttons.
