[SOLVED] IntValidator does not check range correctly after assignment of min/max range from delegate

[serdef]

Hello,

IntValidator behaves strangely when I assign the limits through a delegate :
The value from the model data appears, and I can edit that, but the range is not checked :

• I can enter 8888888888888888888 when range is set to -100,+100.
• when i delete all characters, i can no longer type new digits into the field.

If this same assignment is executed in a separate test, Testscreen1.qml, a simple button onclick handler,
this works fine, I don't see why this works and the other situation not.
When I look with the qml 'live' debug object viewer, the assignments seem to be ok.
In the c++ objects from the qlist in the mode, the properties are QStrings :
Q_PROPERTY(QString prop_min READ getmin WRITE setmin NOTIFY minChanged)
Q_PROPERTY(QString prop_max READ getmax WRITE setmax NOTIFY maxChanged)

(I use string properties as this may later be extended to a hex range as well).

So I would be very happy if an expert here can see what I am doing wrong (be it a bug or the wrong way).

Thank you,
Serge

Solved, the above code was OK !
My test model data was wrong : It had minimum and maximum swapped (min =100, max = -100).
Doh!

This had the effect that I could edit the existing value (that was out of range) without limits, but after deleting all characters i could not enter anything.

Oh well, above code may be useful to someone, it works fine when fed with the correct parameters ;-).
