Added test to cover netgaive size view

Test is similar to TouchWebView.

I don't understand why we should support negative web view sizes. What's the use case?

[Gopal Raghavan]

Same reason why Benjamin insisted for TouchWebView: to catch regression.

Is that generally correct with QML?
If you use negative width and height on a QML image element, do you get the element inverted?

Having a defined behavior for negative size is a good idea. But supporting negative size is another problem altogether.

This is just not needed. Rectangle { width:-200; height:-30000 } is like doing QObject*obj = 0; obj->foo(); it is bad code.

I agree, but does QML raise an error for that at least?

Like Alexis and Benjamin I also fail to see the value of a webview with a negative width/height. As such I don't see what value this test adds that is specific to WebKit.

(Maybe you want to submit a unit test to the qtdeclarative repository to verify QtQuick's behaviour on negative dimensions?)

[Alexis Menard (darktears)]

Then we should probably remove the test of TouchWebView already landed which test negative values.

[Gopal Raghavan]

I would actually like to modify and rewrite these tests to catch the error. Ideally, with negative values, the load should have failed.
What do you think ?

I think it should assert but It should be done in Qt Quick level to my opinion. Not sure if the Qt Quick team want that though. The API allows in theory to set negative size as the width and height are qreal which means double in most cases.

+1 here. I'm failing to see the point of this test...

+1 here as well. Let's do it while refactoring the qml tests. They need some love after the merge of both WebViews.


If no one opposes to, I would like to close this bug.
