I am trying to create a plugin consisting of QML types but no C++ classes. I
built a simple QML file called MyPlugin.qml that starts with “pragma Singleton”
and resides in <mypath>\MyPlugin. My qmldir file consists of
module MyPlugin
singleton MyPlugin 1.0 MyPlugin.qml
When I run
<qtpath>\5.3\mingw482_32\bin\qmlplugindump -nonrelocatable MyPlugin 1.0 .
from <mypath> a plugins.qmltypes file is created with
Module {
Component {
prototype: "QQuickItem"
name: "MyPlugin"
exports: ["MyPlugin -1.-1"]
exportMetaObjectRevisions: [-1]
isComposite: true
isCreatable: false
isSingleton: true
. . .
and all of the methods (corresponding to my functions) and their parameters
have type QVariant.
Is my qmldir correct to generate the plugins.qmltypes file? Why do exports and
exportMetaObjectRevisions have such strange contents? Should these be changed
to “MyPlugin 1.0” and 0, respectively? Should the QVariant types be manually
changed?
Are there any examples of creating and using Qt plugins made entirely with just
QML and no C++? It would be useful to see an example that creates (1) library
files, (2) plugins.qmltypes, and (3) an app using the output of 1 and 2.
Thanks.
Steve
