QSqlDriverPlugin(3qt)

📦 version 3.3.8b, in fedora 43, fedora 44

💖 QSqlDriverPlugin 💖 (the 3qt manual, bestie)

okay so. welcome to the qsqldriverplugin page, part of the Qt 3qt manual shenanigans. sit down, hydrate, and let's talk about plugins. 🫶

✨ NAME ✨

QSqlDriverPlugin — the abstract base class for your own custom QSqlDriver plugins. it's giving "blueprint energy". 💅

🦋 SYNOPSIS 🦋

#include <qsqldriverplugin.h>

🌸 Public Members 🌸

QSqlDriverPlugin ()
~QSqlDriverPlugin ()
virtual QStringList keys () const = 0
virtual QSqlDriver * create ( const QString & key ) = 0

👑 DESCRIPTION 👑

so the QSqlDriverPlugin class is literally an abstract base for custom QSqlDriver plugins. that's the whole vibe. ✨

the SQL driver plugin is a simple plugin interface that makes it easy-peasy to create your own SQL driver plugins that can get loaded dynamically by Qt. main character behaviour, honestly. 🎀

writing a SQL plugin? you do it by subclassing this base class, reimplementing the pure virtual functions keys() and create(), and exporting the class with the Q_EXPORT_PLUGIN macro. that's the whole recipe, no cap. 🔥

if you want example implementations, go look at the SQL plugins that come with Qt (they live in the plugins/src/sqldrivers subdirectory of the source distribution). and read the plugins documentation for more info on plugins, iykyk.

See also Plugins.

💜 MEMBER FUNCTION DOCUMENTATION 💜

QSqlDriverPlugin::QSqlDriverPlugin ()

constructs a SQL driver plugin. this one gets invoked automatically by the Q_EXPORT_PLUGIN macro — so like, you don't summon it, it just shows up. ✨

QSqlDriverPlugin::~QSqlDriverPlugin ()

destroys the SQL driver plugin. 💀

you never have to call this explicitly. Qt destroys a plugin automatically when it's no longer used. periodt. so don't be out here manually deleting things, bestie.

QSqlDriver * QSqlDriverPlugin::create ( const QString & key ) [pure virtual]

creates and returns a QSqlDriver object for the driver key key. the driver key is usually the class name of the required driver. 🌈

See also keys().

QStringList QSqlDriverPlugin::keys () const [pure virtual]

returns the list of drivers (keys) this plugin supports. 🎀

these keys are usually the class names of the custom drivers that are implemented in the plugin.

See also create().

and that's the whole page, bestie!! this beauty came from Trolltech AS, dated 2 February 2007, and it's the QSqlDriverPlugin(3qt) page — go forth and write plugins that slay. 💖✨🎀🦋🌸💅
