In this Python article we are going to talk about How to Create SpinBox in Pyside2, the QSpinBox class provides a spin box widget, QSpinBox allows the user to choose a value by clicking the up/down buttons or pressing up/down on the keyboard to increase/decrease the value currently displayed. The user can also type the value in manually. the spin box supports integer values but can be extended to use different strings with validate(), textFromValue() and valueFromText(). every time the value changes QSpinBox emits valueChanged() and textChanged() signals, the former providing a int and the latter a QString. The textChanged() signal provides the value with both prefix() and suffix() . The current value can be fetched with value() and set with setValue() .

from PySide2.QtWidgets import QApplication, QWidget, QSpinBox, QLabel, QVBoxLayout, QDoubleSpinBox import sys from PySide2.QtGui import QIcon class Window(QWidget): def __init__(self): super().__init__() self.setWindowTitle("Pyside2 SpinBox") self.setGeometry(300,200,300,100) self.setIcon() self.spin_box() self.show() def setIcon(self): appIcon = QIcon("icon.png") self.setWindowIcon(appIcon) def spin_box(self): vbox = QVBoxLayout() self.label = QLabel() self.spinbox = QDoubleSpinBox() self.spinbox.setMinimum(10) self.spinbox.setMaximum(100) self.spinbox.valueChanged.connect(self.spin_value) vbox.addWidget(self.label) vbox.addWidget(self.spinbox) self.setLayout(vbox) def spin_value(self): self.label.setText("Current Value Is : " + str(self.spinbox.value())) myapp = QApplication(sys.argv) window = Window() myapp.exec_() sys.exit() |
OK now in here we are going to set our window title, also we need to set the geometry of the window, like x and y position of the window, also width and height of the window .
|
1 2 |
self.setWindowTitle("Pyside2 SpinBox") self.setGeometry(300,200,300,100) |
Also in this method we have created our method for setting window icon.
|
1 2 3 |
def setIcon(self): appIcon = QIcon("icon.png") self.setWindowIcon(appIcon) |
In here we have created the object of QDoubleSpinBox, and also we have set the minimum and maximum value for the spinbox , you can see that at the bottom of the code we have connected the valueChanged signal of QSpinBox with the spin_value() method that we have created.
|
1 2 3 4 |
self.spinbox = QDoubleSpinBox() self.spinbox.setMinimum(10) self.spinbox.setMaximum(100) self.spinbox.valueChanged.connect(self.spin_value) |
And this is the method that we have already connected this at the top.
|
1 2 |
def spin_value(self): self.label.setText("Current Value Is : " + str(self.spinbox.value())) |
Because we are using QVBoxLayout, now we need to add our widgets in the QVBoxLayout.
|
1 2 |
vbox.addWidget(self.label) vbox.addWidget(self.spinbox) |
Finally, we have entered to the mainloop of the application. The event handling starts from this point. also we have created the object of our window in this class.
|
1 2 3 |
window = Window() myapp.exec_() sys.exit() |
So run the complete code this will be the result
