Hi,
I'm trying to make an undo redo, I manage to have my whole thing working for
user mouse drag n drop, add remove part into my model. One thing that bug me
with the control 2 is the spinbox, the value is bind to the mode and the model
get changed too, not sure this is the optimal way (I so wish we got 2 way
binding like C# one day, this is so deeply needed and not have everybody
reimplement there own way).
SpinBox
{
id: sequenceIndex_
value: opsModel.index
onValueChanged:
{
// This is called before value modified
}
onValueModified:
{
// The value is already modified, how can I get previous value to make
my undo/redo ? seem too late and the value changed as already been called
}
Binding
{
target: ops_model
property: "index"
value: sequenceIndex_.value
}
}
How does one manage to do it with this control?! I guess I will have the same
challenge with the ComboBox and all the selector controls (button are fairly
easy since I can capture the previous value before doing the action).
