Pyqt5 qslider

Widgets are basic building blocks of an application. PyQt5 has a wide range of various widgets, including buttons, check boxes, sliders, or list boxes.

A QCheckBox is a widget that has two states: on and off. It is a box with a label. Checkboxes are typically used to represent features in an application that can be enabled or disabled. We connect the user defined changeTitle method to the stateChanged signal. The changeTitle method will toggle the window title.

The state of the widget is given to the changeTitle method in the state variable. If the widget is checked, we set a title of the window. Otherwise, we set an empty string to the titlebar. A toggle button is a QPushButton in a special mode. It is a button that has two states: pressed and not pressed.

We toggle between these two states by clicking on it.

There are situations where this functionality fits well. In our example, we create three toggle buttons and a QWidget. We set the background colour of the QWidget to black. The toggle buttons will toggle the red, green, and blue parts of the colour value.

The background colour depends on which toggle buttons is pressed. To create a toggle button, we create a QPushButton and make it checkable by calling the setCheckable method.

We connect a clicked signal to our user defined method. We use the clicked signal that operates with a Boolean value. We use style sheets to change the background colour. The stylesheet is updated with setStyleSheet method. A QSlider is a widget that has a simple handle. This handle can be pulled back and forth. This way we are choosing a value for a specific task.

Sometimes using a slider is more natural than entering a number or using a spin box. In our example we will show one slider and one label.Your browser does not seem to support JavaScript.

I'm trying to add some style to a QSlider I want to use a custom image as the handle that the user drags back and forth. While I've figured out how to use style sheets to have a custom icon drawn where the handle should be, the image is being drawn much too small and I cannot figure out how to make it larger.

Setting width and height seem to do nothing. I've tried using image, border-image and background-image, but none give me the ability to set the size of the handle image.

Does anyone know how to do this? Hi Try with this. The height of slider handle is linked to height in QSlider::groove:horizontal. Okay - this helped.

The base size of the image is being set by the groove, but you can also further enlarge the handle image via the margin property on. Qt Forum.

Load Comments.The slider is the classic widget for controlling a bounded value. It lets the user move a slider handle along a horizontal or vertical groove and translates the handle's position into an integer value within the legal range.

QSlider has very few of its own functions; most of the functionality is in QAbstractSlider. The most useful functions are setValue to set the slider directly to some value; triggerAction to simulate the effects of clicking useful for shortcut keys ; setSingleStepsetPageStep to set the steps; and setMinimum and setMaximum to define the range of the scroll bar. QSlider provides methods for controlling tickmarks. You can use setTickPosition to indicate where you want the tickmarks to be, setTickInterval to indicate how many of them you want.

QSlider only provides integer ranges. Note that although QSlider handles very large numbers, it becomes difficult for users to use a slider accurately for very large ranges.

A slider accepts focus on Tab and provides both a mouse wheel and a keyboard interface. The keyboard interface is the following:. This enum specifies where the tick marks are to be drawn relative to the slider's groove and the handle the user moves. This is a value interval, not a pixel interval. If it is 0, the slider will choose between singleStep and pageStep. See also tickPositionsingleStepand pageStep.

The valid values are described by the QSlider::TickPosition enum.
