Qt 5 UiHelpers
The UI Helpers repository contains non-widget based ui classes that are useful for those who intend to develop applications using Qt5/QtQuick 2 but do not want to depend on QtWidgets – mainly desktop applications. Examples of classes are QUndoCommand, QAction, QFileSystemModel, etc.
The work started with the change 15857, when we discussed about moving QUndo* out of QtWidgets. In this change, first we moved these classes to QtGui, then to a new lib inside qtbase. However, it was not considered ideal and the decision was to create a separated repo for these classes, leaving QtWidgets untouched (since the Qt community do not want to introduce new bugs in this lib).
Follows the table of QtWidgets classes that are available in the independent module UiHelpers. Notice we do not want to use the Ui prefix forever ;)
|QtWidget Class||UiHelpers Equivalent||Status|
|QFileSystemModel||UiFileSystemModel||Better example needed.|
|QStandardItemModel||UiStandardItemModel||Need both example and test.|
|QAction||UiAction||Needs code and tests cleanup. Also, an example.|
|QCompleter||UiCompletionModel||Needs tests. Example OK.|
We still doing experiments, far from a stable state. The plan is to go further, provinding an API more suitable to be used with QtQuick 2.
As the QtQuick is now a firs class citizen of the Qt world, we are creating a few plugins that ease the development of more complex applications in QML. The plugins are adaptions of the C++ classes of this module to have a declarative API.
Follows the table of the plugins we'll have and it's status:
|Quick UndoFramework||QML friendly API to use the UndoFramework||WIP|
|Quick CompletionModel||QML model for completion||WIP|
The Qt5 UiHelpers target the following operating systems:
|Windows NT/2K/XP/Vista/7||YES||Tests needed|
|Windows CE||YES||Tests needed|
|Others Unix||YES||All POSIX-compatible|
Getting the source code
The official repositories are at code.qt.io. The qt-project repository accepts contributions, using gerrit code review tool.
git clone git://code.qt.io/playground/uihelpers.git
Qt-project main repository:
git clone ssh://<gerrit username>@codereview.qt.io:29418/playground/uihelpers.git
Building and Installing
To build the module, be sure to have the Qt5 qmake in your PATH then go to the source directory of your local clone of the UiHelpers repository:
make install works as any other Qt 5 module, installing headers to $QTDIR/include/UiHelpers and libUiHelpers to $QTDIR/lib
There are few examples in the repository, contributions are welcome.
Suggestions and contributions are welcome!
After the initial import, patches must go through gerrit:
git push ssh://codereview.qt.io:29418/playground/uihelpers.git refs/for/master
We are using the same commit-template used by Qt 5. So, to make things easier, you can do:
git config commit.template $PATH_TO_YOUR_QT5_REPO/.commit-template
You can easily contact us on email@example.com or #qt-labs freenode - anselmolsm, luisgabriel, mailson, dakerfp, lacerda, cidoca
