Although Qt actually provides a specific font-selection combo box as QFontComboBox. You have probably seen the combo box used for selection of font faces, or size, in word processing applications. The combo box is suited to selection of a choice from a long list of options. ![]()
![]() You can select a single item from the list, with the currently selected item being shown as a label on the widget. The QComboBox is a drop down list, closed by default with an arrow to open it. This means you can test state using state = Qt.Checked. This is the value of these state's respective flags. You don’t need to remember these values, the Qt.Checked namespace variable = 2 for example. You may notice that when the script is running the current state number is displayed as an int with checked = 2, unchecked = 0, and partially checked = 1. SetTriState(True) to set tristate support on a You can also set a checkbox to be tri-state without setting the current state to partially checked by using. If you set the value to Qt.Partiall圜hecked the checkbox will become tristate. A checkbox in this state is commonly shown as a greyed out checkbox, and is commonly used in hierarchical checkbox arrangements where sub-items are linked to parent checkboxes. Namespace flag: PyQt5 flagĪ checkbox that supports a partially-checked ( Qt.Partiall圜hecked) state is commonly referred to as 'tri-state', that is being neither on nor off. SetCheckState you also specify a particular checked state using a Qt. The former accepts either True or False representing checked or unchecked respectively. You can set a checkbox state programmatically using. #HOW TO GET MORE DASHBOARD WIDGETS FOR MAC MAC#QCheckBox on Windows, Mac & Ubuntu Linux. # For tristate: tCheckState(Qt.Partiall圜hecked) You can combine flags together using pipes ( |), however note that youĬan only use vertical or horizontal alignment flag at a time. The flags available for vertical alignment are: PyQt5 flagĬenters vertically in the available space. Justifies the text in the available space. The flags available for horizontal alignment are: PyQt5 flagĬenters horizontally in the available space. The alignment is specified by using a flag from the Qt. This ensures the font face remains in keeping with the desktop conventions. #HOW TO GET MORE DASHBOARD WIDGETS FOR MAC UPDATE#TAlignment(Qt.AlignHCenter | Qt.AlignVCenter)įont tip Note that if you want to change the properties of a widget font it is usually better to get the current font, update it and then apply it back. #HOW TO GET MORE DASHBOARD WIDGETS FOR MAC CODE#Save the following code to a file named app.py and run it to make sure it's working. To experiment with the widgets we'll need a simple application to put them in. Next, we'll step through some of the most commonly used widgets and look at them in more detail. There are far more widgets than this, but they don’t fit so well! You can see them all by checking the Qt documentation. Lets have a look at all the example widgets, from top to bottom: Widget Run it!
