This article is to share with you about the pyqt5 grid layout QGridLayout in Python. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article. Let's take a look at it with the editor.

1. Grid layout QGridLayout

A similar look of grid layout

When using grid layout, you should pay attention to:

1. To import the class library QGridLayout

two。 The index for this layout starts from 0 by default.

3. Instantiate the class before using the grid layout

2. Multi-line text box QTextEdit

Use QTextEdit as a class library

Using a method is similar to directly instantiating a class.

For example:

Tecontent=QTextEdit ()

Third, make an article input interface

Interface effect

Grid layout benefits:

1. We can make a good plan for our control similar to a table.

two。 This layout allows our controls to change as the form changes.

Grid layout Settin

In fact, we can see many methods that we can implement directly through the instantiated objects of the grid layout and directly through the code hints. For example, if we want to set the spatial distance between grids, we can set setSpacing to set it.

For example:

Grid.setSpacing (pixel value of space)

We have to learn from the example, through the way of set can try to set up many other functions.

IV. Summary and emphasis

1. Master the idea of grid layout, master the application of QGridLayout.

two。 Master the use of multiline text boxes for new controls.

3. Learn about new controls according to QTDesigner, or according to the control catalog provided in pyqt5.

This section knowledge source code

Import sysfrom PyQt5.QtWidgets import QApplication,QWidget,QLineEdit,QTextEdit,QLabel,QGridLayout

Class MyClass (QWidget): def _ init__ (self): super (). _ init__ () self.initUI ()

Def initUI (self): self.setWindowTitle ("Liu Jinyu programming") self.setGeometry (300200400300)

Lbltitle=QLabel (title) lblauthor=QLabel (author) lblcontent=QLabel (content)

Letitle=QLineEdit () leauthor=QLineEdit () tecontent=QTextEdit ()

Grid=QGridLayout (self) grid.setSpacing (20)

Grid.addWidget (lbltitle,0,0) grid.addWidget (letitle,0,1)

Grid.addWidget (lblauthor,1,0) grid.addWidget (leauthor,1,1)

Grid.addWidget (lblcontent,2,0) grid.addWidget (tecontent,2,1)

Self.show ()

If _ name__== "_ _ main__": app=QApplication (sys.argv) mc=MyClass () app.exec_ ()

This is what the pyqt5 grid layout QGridLayout looks like in Python. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
