\title Specifying Text Editor Settings
Set the font preferences and apply color schemes for syntax highlighting,
diff editor, and code analysis results in \uicontrol Edit >
\uicontrol Preferences > \uicontrol {Text Editor} >
\uicontrol {Font & Colors}.
\image qtcreator-font-colors.png "Text editor preferences"
\section2 Configuring Fonts
You can select the font family and size. You can specify a zoom setting in
percentage for viewing the text. You can also zoom in or out by pressing
\key {Ctrl++} or \key {Ctrl+-}, or by pressing \key Ctrl and rolling
the mouse button up or down. To disable the mouse wheel function, select
\uicontrol Edit > \uicontrol Preferences > \uicontrol {Text Editor} >
\uicontrol Behavior and deselect the
\uicontrol {Enable scroll wheel zooming} check box.
Antialiasing is used by default to make text look smoother and more readable
on the screen. Deselect the \uicontrol Antialias check box to turn off
antialiasing.
\section2 Defining Color Schemes
You can select one of the predefined color schemes or create customized
color schemes.
To create a color scheme:
\list 1
\li Select \uicontrol Edit > \uicontrol Preferences >
\uicontrol {Text Editor} > \uicontrol {Fonts & Color} >
\uicontrol Copy.
\li Enter a name for the color scheme and click \uicontrol OK.
\li In the \uicontrol Foreground field, specify the color of the selected
code element or message.
\li In the \uicontrol Background field, select the background
color for the code element or message.
The backgound of the \uicontrol Text element determines the background of the
code editor.
\li In \uicontrol Font, select \uicontrol Bold or \uicontrol Italic to
format the text of the selected code element or message by making it
bold or italic.
\li In \uicontrol Underline, select the color and style to use for
underlining code elements or messages.
\endlist
When you copy code from \QC, it is copied in both plain text and HTML
format. The latter makes sure that syntax highlighting is preserved when
pasting to a rich-text editor.
\section2 Exporting and Importing Color Schemes
To share color schemes with others, export and import them as XML files.
To export a color scheme, select \uicontrol Edit > \uicontrol Preferences >
\uicontrol {Text Editor} > \uicontrol {Fonts & Color} > \uicontrol Export,
and then select the filename and location for the XML file.
To import a color scheme, select \uicontrol Import, and then select the XML
file to import. In the \uicontrol {Import Color Scheme} dialog, enter a name
for the color scheme in \uicontrol {Color scheme name}:
\image qtcreator-import-color-scheme.png "Import Color Scheme dialog"
When you select \uicontrol OK, the color scheme is added to the list of
color schemes in the \uicontrol {Fonts & Color} tab.
\section2 File Encoding
To define the default file encoding, select \uicontrol Edit >
\uicontrol Preferences > \uicontrol {Text Editor} > \uicontrol Behavior, and
then select a suitable option in \uicontrol {Default encoding}.
\image qtcreator-options-texteditor-behavior-file-encodings.png "File encoding preferences"
Qt 5 and Qt 6 require UTF-8 encoded source files, and therefore the default
encoding is set to \uicontrol UTF-8.
Detecting the correct encoding is tricky, so \QC will not try to do so.
Instead, it displays the following error message when you try to edit a file
that is not UTF-8 encoded: \uicontrol {Error: Could not decode "filename" with
"UTF-8"-encoding. Editing not possible.}
To resolve the issue, use a file conversion tool to convert the file
encoding to UTF-8 when developing Qt 5 applications. Otherwise, conversion
of string constants to QStrings might not work as expected.
If you develop only Qt 4 applications or other than Qt applications, you
can set other encoding options as the default encoding. Select the
\uicontrol System option to use the file encoding used by your system.
