[beginner] action type property
-
Hi,
I'm really beginner, so maybe my question is stupid, but i cant google the answer.
I want to define my own "windget" witch should have action typed property
so in file SelField.qml i have@Item{
id: selFieldproperty string labelText property string fieldText property string placeholderText property action btnAction
...
@Now I trying to use it
@ SelField {
id: firmwareSelection
btnAction: openFirmwareAction
labelText: qsTr("Firmware file path:")
placeholderText: qsTr("<Select file>")
fieldText: firmwarePath
}@But component could not be loaded
"QQmlApplicationEngine failed to load component
file:///C:/Users/kku/Documents/hobby/elektronika/my_projects/_qt/FirmwareUpdater/build-FirmwareUpdater-Desktop_Qt_5_1_1_MinGW_32bit-Debug/qml/FirmwareUpdater/MainView.qml:125 Type SelField unavailable
file:///C:/Users/kku/Documents/hobby/elektronika/my_projects/_qt/FirmwareUpdater/build-FirmwareUpdater-Desktop_Qt_5_1_1_MinGW_32bit-Debug/qml/FirmwareUpdater/SelField.qml:11 Expected property type"When I remove
@ Item{
id: selFieldproperty string labelText property string fieldText property string placeholderText
// property action btnAction
@I can use selField without problems
@ SelField {
id: firmwareSelection
//btnAction: openFirmwareAction
labelText: qsTr("Firmware file path:")
placeholderText: qsTr("<Select file>")
fieldText: firmwarePath
}@What do I wrong, I just want to assign this property to the button...
@ Button {
id: button1
action: btnAction
text: qsTr("...")
anchors.right: parent.right
anchors.rightMargin: 0
width: 50
}@Does only string type could be use in "property" statement?
Thank you in advance

Here is the list: "link":http://qt-project.org/doc/qt-5.0/qtqml/qtqml-typesystem-basictypes.html. Be sure to check out the docs first, Qt has very good documentation.

Hi,
Thanks for replay, I got it, but how about action type
"link.":http://qt-project.org/doc/qt-4.8/qml-action.html
Why it's not mentioned in list provided by you? It's also described as basic type.
Does qt 5.0 is not compatible with 4.8 ?
Thank you in advance
KrzysiekPS
another list containing action as basic type
"link":http://qt-project.org/doc/qt-4.8/qdeclarativebasictypes.html -
It is fully compatible ;) In Qt5 you can choose between QtQuick1 (sometimes called QtDeclarative) and QtQuick2 (found in QtQuick and QtQml modules). They are not source compatible, indeed.
I've never used the action property, so I can't say what happened to it in QtQuick2. Try mimicking it with "var" type.

Hi,
I just checked source cod of standard button, and similar property type is "Action" instead of "action" :)
Now it works perfect....Regards
