\title Specifying Text Editor Settings
Set the font preferences and apply color schemes for syntax highlighting in
\uicontrol Tools > \uicontrol Options > \uicontrol {Text Editor} >
\uicontrol {Font & Colors}.
\image qtcreator-font-colors.png "Text editor options"
\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 Tools > \uicontrol Options > \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 for syntax highlighting
or create customized color schemes. The color schemes apply to highlighting
both C++ and QML files and generic files.
To create a color scheme:
\list 1
\li Select \uicontrol Tools > \uicontrol Options >
\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.
\li In the \uicontrol Background field, select the background
color for the code element.
The backgound of the \uicontrol Text element determines the background of the
code editor.
\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 File Encoding
To define the default file encoding, select \uicontrol Tools >
\uicontrol Options > \uicontrol {Text Editor} > \uicontrol Behavior, and
then select a suitable option in \uicontrol {Default encoding}.
Qt 5 requires UTF-8 encoded source files, and therefore the default encoding
was changed from \uicontrol System to \uicontrol UTF-8 in \QC version 2.6.
However, the \uicontrol {Default encoding} field still displays the value
\uicontrol System if the default system encoding is set to 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.
