Hi,
maybe the question was already raised and I just missed that. I did not find
anything so far.
Is there a way in QML to create custom setters or getters to properties?
The issue I am facing is a, to be able to control the setting of a custom
property, based on the component internal state.
The snippet is not complete nor working, but should show the issue:
Foo {
id: foo
property bool checked: false
property bool _someCondition: (a < b)
}
Rectangle {
color: foo.checked ? "green" : "red"
}
MouseArea {
onClicked: foo.checked = !foo.checked
}
So clicking on the MouseArea toggles the foo.checked, but the actual
foo.checked should be only changed if foo._someCondition is true. So the
Rectangle's color binding should only be evaluated in case the foo.checked
really changes. Resetting the property after doing some onCheckedChanged is
not what I want.
I only found a clean solution with creating a custom setter here, which is of
course possible when creating a custom c++ class for Foo{}.
Would be nice to avoid this, any ideas? Maybe there is a plain simple solution
and my QML knowledge is just too limited :-)
Thanks,
Johannes
