Detailed Description

QQmlSignalNames contains a list of helper methods to manipulate signal names. Always try to use the most specific one, as combining them might lead to incorrect results like wrong upper/lower case, for example.

Member Function Documentation

◆ addPrefixToPropertyName()

QString QQmlSignalNames::addPrefixToPropertyName	(	QStringView	prefix,
		QStringView	propertyName )

static

Concatenate a prefix to a property name and uppercases the first letter of the property name.

Definition at line 84 of file qqmlsignalnames.cpp.

References QString::append(), changeCaseOfFirstLetter(), QStringView::size(), QStringView::toString(), and ToUpper.

Here is the call graph for this function:

◆ badHandlerNameToSignalName()

std::optional< QString > QQmlSignalNames::badHandlerNameToSignalName ( QStringView handler )

static

Returns a signal name from handlerName string. Do not use it on changed handlers, see changedHandlerNameToSignalName for that! Accepts improperly capitalized handler names and incorrectly resolves signal names that start with '_' or '$'.

Definition at line 198 of file qqmlsignalnames.cpp.

◆ changedHandlerNameToPropertyName() [1/2]

std::optional< QString > QQmlSignalNames::changedHandlerNameToPropertyName ( QStringView handler )

static

Returns a property name from changedHandler. This fails for property names starting with an upper-case letter, as it will lower-case it in the process.

References changedSignalNameToPropertyName(), handlerNameToSignalName(), and isChangedHandlerName().

Here is the caller graph for this function:

◆ changedHandlerNameToPropertyName() [2/2]

static std::optional< QByteArray > QQmlSignalNames::changedHandlerNameToPropertyName ( QUtf8StringView handler )

static

◆ changedHandlerNameToSignalName()

std::optional< QString > QQmlSignalNames::changedHandlerNameToSignalName ( QStringView handler )

static

Returns a signal name from changedHandlerName string. Makes sure not to lowercase the 'C' from Changed.

Definition at line 216 of file qqmlsignalnames.cpp.

◆ changedSignalNameToPropertyName() [1/2]

std::optional< QString > QQmlSignalNames::changedSignalNameToPropertyName ( QStringView signalName )

static

Obtain a propertyName from its changed signal handler. Do not call this on a value obtained from handlerNameToSignalName! Instead use changedHandlerNameToPropertyName() directly. Otherwise you might end up with a wrong capitalization of _Changed for "on_Changed", for example.

Definition at line 128 of file qqmlsignalnames.cpp.
