If you use the \l{Parsing C++ Files with the Clang Code Model}
{Clang code model} to parse the C++ files, the
\l{http://clang.llvm.org/diagnostics.html}{Clang fix-it hints}
that have been integrated into \QC are also available to you. In addition to
the standard ways of activating refactoring actions, you can select the
actions that are applicable on a line in the context menu in the left margin
of the code editor.
\section2 Refactoring C++ Code
You can apply the following types of refactoring actions to C++ code:
\list
\li Change binary operands
\li Simplify if and while conditions (for example, move declarations out
of if conditions)
\li Modify strings (for example, set the encoding for a string to
Latin-1, mark strings translatable, and convert symbol names to
camel case)
\li Create variable declarations
\li Create function declarations and definitions
\endlist
The following table summarizes the refactoring actions for C++ code. The
action is available when the cursor is in the position described in the
Activation column.
\table
\header
\li Refactoring Action
\li Description
\li Activation
\row
\li Add Curly Braces

\code
if (a) {
b;
}
\endcode
\li \c if
\row
\li Move Declaration out of Condition
\li Moves a declaration out of an if or while condition to simplify
the condition. For example, rewrites

Type name = foo;
if (name) {}
\endcode
\li Name of the introduced variable
\row
\li Rewrite Condition Using ||

\row
\li Split if Statement
\li Splits an if statement into several statements. For example,
rewrites:
\code
if (something && something_else) {
}
\endcode
as
\code
if (something) {
if (something_else) {
}
}
\endcode
and
\code
if (something || something_else)
x;
\endcode
with
\code
if (something)
x;
else if (something_else)

\endcode
as
\code
@"abcd"
\endcode
\li String literal
\row
\li Enclose in QLatin1Char()
\li Sets the encoding for a character to Latin-1, unless the
character is already enclosed in QLatin1Char, QT_TRANSLATE_NOOP,
tr, trUtf8, QLatin1Literal, or QLatin1String. For example,
rewrites

\endcode
as
\code
QLatin1Char('a')
\endcode
\li String literal
\row
\li Enclose in QLatin1String()

\code
QLatin1String("abcd")
\endcode
\li String literal
\row
\li Mark as Translatable
\li Marks a string translatable. For example, rewrites \c "abcd"

function in the \uicontrol {Extract Function Refactoring}
dialog.
\li Block of code selected
\row
\li Extract Constant as Function Parameter
\li Replaces the selected literal and all its occurrences with the
function parameter \c{newParameter}. The parameter
\c{newParameter} will have the original literal as the default
value.
\li Block of code selected
\row
\li Add Local Declaration
\li Adds the type of an assignee, if the type of the right-hand
side of the assignment is known. For example, rewrites
\code

\endcode
where Type is the return type of \c {foo()}
\li Assignee
\row
\li Convert to Camel Case

\title Applying Refactoring Actions
\QC allows you to quickly and conveniently apply actions (quick fixes)
to refactor your code by selecting them in a context menu. The actions
available depend on the position of the cursor in the code editor.
\if defined(qtcreator)
To apply refactoring actions to C++ code, right-click an operand,
conditional statement, string, or name to open a context menu.
\endif
To apply refactoring actions to QML code, right-click an item ID or name.
In the context menu, select \uicontrol {Refactoring} and then select a
refactoring action.
You can also press \key {Alt+Enter} to open a context menu that contains
refactoring actions available in the current cursor position.
\if defined(qtcreator)
\section1 Creating Functions
You can apply refactoring actions to implement member functions, insert
virtual functions of base classes, create getter and setter functions,
and generate constructors. You can specify settings for generating the
functions either globally for all projects or separately for each project
in the \l{Specifying Settings}{build and run} settings of the project.
\section2 Implementing Member Functions
You can apply the \uicontrol {Create Implementations for Member Functions}
refactoring action to create implementations for all member functions in
one go. In the \uicontrol {Member Function Implementations} dialog, you can
specify whether the member functions are generated inline or outside the
class.
\image qtcreator-refactoring-member-function-implementations.png "Implement Member Functions dialog"
\section2 Inserting Virtual Functions
You can apply the \uicontrol {Insert Virtual Functions of Base Classes}
refactoring action to insert declarations and the corresponding definitions
inside or outside the class or in an implementation file (if it exists).
\image qtcreator-refactoring-virtual-function-dialog.png "Insert Virtual Functions dialog"
Select the functions to insert in the list of available functions. You can
filter the list and hide reimplemented functions from it.
You can add \e virtual or the \e override equivalent to the function
declaration.
\section2 Creating Getters and Setters
You can apply the \uicontrol {Create Getter and Setter Member Functions}
refactoring action to create either both getter and setter member functions
for member variables or only a getter or setter.
\image qtcreator-refactoring-getters-and-setters.png "Getters and Setters dialog"
\section2 Generating Constructors
You can apply the \uicontrol {Generate Constructor} refactoring action to
create a public, protected, or private constructor for a class. Select the
class members to initialize in the constructor. Drag and drop the parameters
to specify their order in the constructor.
\image qtcreator-refactoring-constructor.png "Constructor dialog"
\section1 Specifying Settings for Refactoring Actions
You can specify settings for the refactoring actions either globally for
all projects or separately for each project. To specify global options,
select \uicontrol Tools > \uicontrol Options > \uicontrol C++ >
\uicontrol {Quick Fixes}.
To specify custom settings for a particular project, select
\uicontrol Projects > \uicontrol {Project Settings} >
\uicontrol {Quick Fixes} > \uicontrol {Custom Settings}.
\image qtcreator-refactoring-options-locations.png "Quick Fixes settings"
To revert to global settings, select \uicontrol {Reset to Global}. To
delete the custom settings, select \uicontrol {Delete Custom Settings File}.
\section2 Function Locations
In the \uicontrol {Generated Function Locations} group, you can determine
whether refactoring actions should generate getter and setter functions
in the header file (inside or outside the class) or in the implementation
file.
\section2 Function Names and Attributes
In the \uicontrol {Getter Setter Generation Properties} group, you can
specify additional settings for getter and setter names, attributes, and
parameters. You can specify that setter functions should be created as
\e slots and that signals should be generated with the new value as a
parameter.
\image qtcreator-refactoring-options-generation.png "Getter and Setter generation settings"
\section2 Namespace Handling
In the \uicontrol {Missing Namespace Handling} group, select whether to
generate missing namespaces, add \c {using namespace} where necessary, or
rewrite types to match the existing namespaces.
\image qtcreator-refactoring-options-namespaces.png "Namespace handling settings"
\section2 Custom Parameter Types
In the \uicontrol {Custom Getter Setter Templates} group, specify how the
code of a getter or setter function for a certain data type should look
like. This is necessary for types where assignment cannot use \c operator=,
as in the pre-defined settings for \c unique_ptr or where \c operator== is
not suitable for comparison, as in the pre-defined settings for
floating-point types. For example, if you have a special type \c MyClass,
you can specify that a function, \c myCompare, should be used for comparison
rather than the default of \c ==.
To specify special handling for a custom parameter type, select
\uicontrol Add and set the parameter type, comparison, return expression,
and return type. In the \uicontrol {Return type} field, you can use \c <new>
and \c <cur> to access the parameter and current value. Use \c <type> to
access the type and \c <T> for the template parameter.
\image qtcreator-refactoring-options-templates.png "Settings for handling custom parameter types"
Usually, arguments are passed by using a \c const reference. To pass
arguments of a particular type as values, list them in the
\uicontrol {Value types} field. Namespaces and template arguments are
removed. The real Type must contain the given Type. For example, \c int
matches \c int32_t but not \c vector<int>, and \c vector matches
\c {std::pmr::vector<int>} but not \c {std::optional<vector<int>>}.

that have been integrated into \QC are also available to you. In addition to
the standard ways of activating refactoring actions, you can select the
actions that are applicable on a line in the context menu in the left margin
of the code editor.
\section2 Refactoring C++ Code
You can apply the following types of refactoring actions to C++ code:
\list
\li Change binary operands
\li Simplify if and while conditions (for example, move declarations out
of if conditions)
\li Modify strings (for example, set the encoding for a string to
Latin-1, mark strings translatable, and convert symbol names to
camel case)
\li Create variable declarations
\li Create function declarations and definitions
\endlist
The following table summarizes the refactoring actions for C++ code. The
action is available when the cursor is in the position described in the
Activation column.
\table
\header
\li Refactoring Action
\li Description
\li Activation
\row
\li Add Curly Braces
\li Adds curly braces to an if statement that does not contain a
compound statement. For example, rewrites
\code
if (a)
b;
\endcode
as
\code
if (a) {
b;
}
\endcode
\li \c if
\row
\li Move Declaration out of Condition
\li Moves a declaration out of an if or while condition to simplify
the condition. For example, rewrites
\code
if (Type name = foo()) {}
\endcode
as
\code
Type name = foo;
if (name) {}
\endcode
\li Name of the introduced variable
\row
\li Rewrite Condition Using ||
\li Rewrites the expression according to De Morgan's laws. For
example, rewrites:
\code

\endcode
as
\code
!(a || b)
\endcode
\li \c &&
\row
\li Rewrite Using \e operator
\li Rewrites an expression negating it and using the inverse
operator. For example, rewrites:
\list
\li \code
a op b
\endcode
as
\code
!(a invop b)
\endcode
\li \code
(a op b)
\endcode
as
\code
!(a invop b)
\endcode
\li \code
!(a op b)
\endcode
as
\code
(a invob b)
\endcode
\endlist
\li \c {<=}, \c {<}, \c {>}, \c {>=}, \c {==} or \c {!=}
\row
\li Split Declaration

\endcode
as
\code
int *a;
int b;
\endcode
\li Type name or variable name
\row
\li Split if Statement
\li Splits an if statement into several statements. For example,
rewrites:
\code
if (something && something_else) {
}
\endcode
as
\code
if (something) {
if (something_else) {
}
}
\endcode
and
\code
if (something || something_else)
x;
\endcode
with
\code
if (something)
x;
else if (something_else)
x;
\endcode
\li \c && or \c ||

QLatin1Literal("abcd")
\endcode
as
\code
@"abcd"
\endcode
\li String literal
\row
\li Enclose in QLatin1Char()
\li Sets the encoding for a character to Latin-1, unless the
character is already enclosed in QLatin1Char, QT_TRANSLATE_NOOP,
tr, trUtf8, QLatin1Literal, or QLatin1String. For example,
rewrites
\code
'a'
\endcode
as
\code
QLatin1Char('a')
\endcode
\li String literal
\row
\li Enclose in QLatin1String()

\endcode
as
\code
QLatin1String("abcd")
\endcode
\li String literal
\row
\li Mark as Translatable
\li Marks a string translatable. For example, rewrites \c "abcd"

For example, rewrites
\code
Class Foo {
void bar();
};
\endcode
as (inside class)
\code
Class Foo {
void bar() {
}
};
\endcode
as (outside class)

\li Replaces the selected literal and all its occurrences with the
function parameter \c{newParameter}. The parameter
\c{newParameter} will have the original literal as the default
value.
\li Block of code selected
\row
\li Add Local Declaration
\li Adds the type of an assignee, if the type of the right-hand
side of the assignment is known. For example, rewrites
