Detailed Description

A Pool of Page items, pages will be unique per url and the items will be kept around unless explicitly deleted.

Instances are C++ owned and can be deleted only manually using deletePage() Instance are unique per url: if you need 2 different instance for a page url, you should instantiate them in the traditional way or use a different PagePool instance.

Property Documentation

◆ cachePages

bool PagePool::cachePages
readwrite

If true (default) the pages will be kept around, will have C++ ownership and only one instance per page will be created.

If false the pages will have Javascript ownership (thus deleted on pop by the page stacks) and each call to loadPage will create a new page instance. When cachePages is false, Components get cached nevertheless.

Definition at line 56 of file pagepool.h.

◆ items

QList< QObject * > PagePool::items
read

All items loaded/managed by the PagePool.

Since
5.84

Definition at line 41 of file pagepool.h.

◆ lastLoadedItem

QQuickItem * PagePool::lastLoadedItem
read

The last item that was loaded with @loadPage.

Definition at line 35 of file pagepool.h.

◆ lastLoadedUrl

QUrl PagePool::lastLoadedUrl
read

The last url that was loaded with @loadPage.

Useful if you need to have a "checked" state to buttons or list items that load the page when clicked.

Definition at line 30 of file pagepool.h.

◆ urls

QList< QUrl > PagePool::urls
read

All page URLs loaded/managed by the PagePool.

Since
5.84

Definition at line 47 of file pagepool.h.

Member Function Documentation

◆ clear()

void PagePool::clear ( )

Deletes all pages managed by the pool.

Definition at line 277 of file pagepool.cpp.

◆ contains()

bool PagePool::contains ( const QVariant page) const
Returns
true if the is managed by the PagePool
Parameters
thepage can be either a QQuickItem or an url

Definition at line 224 of file pagepool.cpp.

◆ deletePage()

void PagePool::deletePage ( const QVariant page)

Deletes the page (only if is managed by the pool.

Parameters
pageeither the url or the instance of the page

Definition at line 238 of file pagepool.cpp.

◆ isLocalUrl()

bool PagePool::isLocalUrl ( const QUrl url)
Returns
true if the url identifies a local resource (local file or a file inside Qt's resource system). False if the url points to a network location

Definition at line 209 of file pagepool.cpp.

◆ loadPage()

QQuickItem * PagePool::loadPage ( const QString url,
QJSValue  callback = QJSValue() 
)

Returns the instance of the item defined in the QML file identified by url, only one instance will be made per url if cachePAges is true.

If the url is remote (i.e. http) don't rely on the return value but us the async callback instead.

Parameters
urlfull url of the item: it can be a well formed Url, an absolute path or a relative one to the path of the qml file the PagePool is instantiated from
callbackIf we are loading a remote url, we can't have the item immediately but will be passed as a parameter to the provided callback. Normally, don't set a callback, use it only in case of remote urls
Returns
the page instance that will have been created if necessary. If the url is remote it will return null, as well will return null if the callback has been provided

Definition at line 66 of file pagepool.cpp.

◆ pageForUrl()

QQuickItem * PagePool::pageForUrl ( const QUrl url) const
Returns
The page associated with a given URL, nullptr if there is no correspondence

Definition at line 219 of file pagepool.cpp.

◆ resolvedUrl()

QUrl PagePool::resolvedUrl ( const QString file) const
Returns
full url from an absolute or relative path

Definition at line 196 of file pagepool.cpp.

◆ urlForPage()

QUrl PagePool::urlForPage ( QQuickItem item) const
Returns
The url of the page for the given instance, empty if there is no correspondence
