Detailed Description

The PySide2.QtWidgets.QToolTip class provides tool tips (balloon help) for any widget.

The tip is a short piece of text reminding the user of the widget’s function. It is drawn immediately below the given position in a distinctive black-on-yellow color combination. The tip can be any rich text formatted string.

Rich text displayed in a tool tip is implicitly word-wrapped unless specified differently with <p style='white-space:pre'> .

The simplest and most common way to set a widget’s tool tip is by calling its QWidget.setToolTip() function.

It is also possible to show different tool tips for different regions of a widget, by using a PySide2.QtGui.QHelpEvent of type QEvent.ToolTip . Intercept the help event in your widget’s PySide2.QtWidgets.QWidget.event() function and call QToolTip.showText() with the text you want to display. The Tooltips example illustrates this technique.

If you are calling QToolTip.hideText() , or QToolTip.showText() with an empty string, as a result of a ToolTip -event you should also call PySide2.QtCore.QEvent.ignore() on the event, to signal that you don’t want to start any tooltip specific modes.

Note that, if you want to show tooltips in an item view, the model/view architecture provides functionality to set an item’s tool tip; e.g., the QTableWidgetItem.setToolTip() function. However, if you want to provide custom tool tips in an item view, you must intercept the help event in the QAbstractItemView.viewportEvent() function and handle it yourself.

The default tool tip color and font can be customized with PySide2.QtWidgets.QToolTip.setPalette() and PySide2.QtWidgets.QToolTip.setFont() . When a tooltip is currently on display, PySide2.QtWidgets.QToolTip.isVisible() returns true and PySide2.QtWidgets.QToolTip.text() the currently visible text.

Note

Tool tips use the inactive color group of PySide2.QtGui.QPalette , because tool tips are not active windows.

QWidget.toolTip QAction.toolTip Tool Tips Example

static PySide2.QtWidgets.QToolTip.font()
Return type:PySide2.QtGui.QFont

Returns the font used to render tooltips.

static PySide2.QtWidgets.QToolTip.hideText()

Hides the tool tip. This is the same as calling PySide2.QtWidgets.QToolTip.showText() with an empty string.

static PySide2.QtWidgets.QToolTip.isVisible()
Return type:PySide2.QtCore.bool

Returns true if this tooltip is currently shown.

static PySide2.QtWidgets.QToolTip.palette()
Return type:PySide2.QtGui.QPalette

Returns the palette used to render tooltips.

Note

Tool tips use the inactive color group of PySide2.QtGui.QPalette , because tool tips are not active windows.

static PySide2.QtWidgets.QToolTip.setFont(arg__1)
Parameters:arg__1PySide2.QtGui.QFont

Sets the font used to render tooltips.

static PySide2.QtWidgets.QToolTip.setPalette(arg__1)
Parameters:arg__1PySide2.QtGui.QPalette

Sets the palette used to render tooltips.

Note

Tool tips use the inactive color group of PySide2.QtGui.QPalette , because tool tips are not active windows.

static PySide2.QtWidgets.QToolTip.showText(pos, text, w, rect)
Parameters:

Shows text as a tool tip, with the global position pos as the point of interest. The tool tip will be shown with a platform specific offset from this point of interest.

If you specify a non-empty rect the tip will be hidden as soon as you move your cursor out of this area.

The rect is in the coordinates of the widget you specify with w . If the rect is not empty you must specify a widget. Otherwise this argument can be 0 but it is used to determine the appropriate screen on multi-head systems.

If text is empty the tool tip is hidden. If the text is the same as the currently shown tooltip, the tip will not move. You can force moving by first hiding the tip with an empty text, and then showing the new tip at the new position.

static PySide2.QtWidgets.QToolTip.showText(pos, text, w, rect, msecShowTime)
Parameters:

This is an overloaded function.

This is similar to QToolTip.showText (pos , text , w , rect ) but with an extra parameter msecDisplayTime that specifies how long the tool tip will be displayed, in milliseconds.

static PySide2.QtWidgets.QToolTip.showText(pos, text[, w=nullptr])
Parameters:

This is an overloaded function.

This is analogous to calling QToolTip.showText (pos , text , w , QRect())

static PySide2.QtWidgets.QToolTip.text()
Return type:unicode

Returns the tooltip text, if a tooltip is visible, or an empty string if a tooltip is not visible.
