Detailed Description#
If you only need to show plain text in an item, consider using QGraphicsSimpleTextItem
instead.
To set the item’s text, pass a QString to QGraphicsTextItem
‘s constructor, or call setHtml()
/ setPlainText()
.
QGraphicsTextItem
uses the text’s formatted size and the associated font to provide a reasonable implementation of boundingRect()
, shape()
, and contains()
. You can set the font by calling setFont()
.
It is possible to make the item editable by setting the Qt::TextEditorInteraction flag using setTextInteractionFlags()
.
The item’s preferred text width can be set using setTextWidth()
and obtained using textWidth()
.
Note
In order to align HTML text in the center, the item’s text width must be set. Otherwise, you can call adjustSize()
after setting the item’s text.
Note
QGraphicsTextItem
accepts hover events
by default. You can change this with setAcceptHoverEvents()
.

PySide6.QtWidgets.QGraphicsItem
Constructs a QGraphicsTextItem
. parent
is passed to QGraphicsItem
‘s constructor.

as the default plain text. parent
is passed to QGraphicsItem
‘s constructor.

- PySide6.QtWidgets.QGraphicsTextItem.adjustSize()#
Adjusts the text item to a reasonable size.
- PySide6.QtWidgets.QGraphicsTextItem.defaultTextColor()#
- Return type:
Returns the default text color that is used for unformatted text.

- PySide6.QtWidgets.QGraphicsTextItem.document()#
- Return type:
Returns the item’s text document.
See also
- PySide6.QtWidgets.QGraphicsTextItem.font()#
- Return type:
Returns the item’s font, which is used to render the text.

- PySide6.QtWidgets.QGraphicsTextItem.linkActivated(arg__1)#
- Parameters:
arg__1 – str
This signal is emitted when the user clicks on a link on a text item that enables Qt::LinksAccessibleByMouse or Qt::LinksAccessibleByKeyboard. link
is the link that was clicked.

- PySide6.QtWidgets.QGraphicsTextItem.linkHovered(arg__1)#
- Parameters:
arg__1 – str
This signal is emitted when the user hovers over a link on a text item that enables Qt::LinksAccessibleByMouse. link
is the link that was hovered over.

- PySide6.QtWidgets.QGraphicsTextItem.openExternalLinks()#
- Return type:
bool
See also
- PySide6.QtWidgets.QGraphicsTextItem.setDefaultTextColor(c)#
- Parameters:
Sets the color for unformatted text to col
.

- PySide6.QtWidgets.QGraphicsTextItem.setDocument(document)#
- Parameters:
document –
PySide6.QtGui.QTextDocument
Sets the text document document
on the item.

- PySide6.QtWidgets.QGraphicsTextItem.setExtension(extension, variant)#
- Parameters:
extension –
Extension
variant – object
- PySide6.QtWidgets.QGraphicsTextItem.setFont(font)#
- Parameters:
font –
PySide6.QtGui.QFont
Sets the font used to render the text item to font
.
See also
- PySide6.QtWidgets.QGraphicsTextItem.setHtml(html)#
- Parameters:
html – str
Sets the item’s text to text
, assuming that text is HTML formatted. If the item has keyboard input focus, this function will also call ensureVisible()
to ensure that the text is visible in all viewports.

toHtml()
hasFocus()
QGraphicsSimpleTextItem
- PySide6.QtWidgets.QGraphicsTextItem.setOpenExternalLinks(open)#
- Parameters:
open – bool
See also
- PySide6.QtWidgets.QGraphicsTextItem.setPlainText(text)#
- Parameters:
text – str
Sets the item’s text to text
. If the item has keyboard input focus, this function will also call ensureVisible()
to ensure that the text is visible in all viewports.
See also
toHtml()
hasFocus()
- PySide6.QtWidgets.QGraphicsTextItem.setTabChangesFocus(b)#
- Parameters:
b – bool
If b
is true, the Tab key will cause the widget to change focus; otherwise, the tab key will insert a tab into the document.
In some occasions text edits should not allow the user to input tabulators or change indentation using the Tab key, as this breaks the focus chain. The default is false.

tabChangesFocus()
ItemIsFocusable
textInteractionFlags()
- PySide6.QtWidgets.QGraphicsTextItem.setTextCursor(cursor)#
- Parameters:
cursor –
PySide6.QtGui.QTextCursor
See also
- PySide6.QtWidgets.QGraphicsTextItem.setTextInteractionFlags(flags)#
- Parameters:
flags – Combination of
Qt.TextInteractionFlag
Sets the flags flags
to specify how the text item should react to user input.
The default for a QGraphicsTextItem
is Qt::NoTextInteraction. This function also affects the ItemIsFocusable QGraphicsItem
flag by setting it if flags
is different from Qt::NoTextInteraction and clearing it otherwise.
By default, the text is read-only. To transform the item into an editor, set the Qt::TextEditable flag.
See also
- PySide6.QtWidgets.QGraphicsTextItem.setTextWidth(width)#
- Parameters:
width – float
Sets the preferred width for the item’s text. If the actual text is wider than the specified width then it will be broken into multiple lines.
If width
is set to -1 then the text will not be broken into multiple lines unless it is enforced through an explicit line break or a new paragraph.
The default value is -1.
Note that QGraphicsTextItem
keeps a QTextDocument internally, which is used to calculate the text width.

- PySide6.QtWidgets.QGraphicsTextItem.supportsExtension(extension)#
- Parameters:
extension –
Extension
- Return type:
bool
- PySide6.QtWidgets.QGraphicsTextItem.tabChangesFocus()#
- Return type:
bool
Returns true
if the Tab key will cause the widget to change focus; otherwise, false is returned.
By default, this behavior is disabled, and this function will return false.

Returns the current text interaction flags.
See also
- PySide6.QtWidgets.QGraphicsTextItem.textWidth()#
- Return type:
float
Returns the text width.
The width is calculated with the QTextDocument that QGraphicsTextItem
keeps internally.
