Problem using SVGs in a BorderImage on the N950
-
Hi,
I've been using SVGs in my BorderImages on Symbian like this:
@
BorderImage {
source: "border.svg"
sourceSize: Qt.size(10, 10)
width: 100
height: sourceSize.height
border {
top: 1.5
right: 1.5
bottom: 1.5
left: 1
}
}
@This rasterizes the SVG in the size I want and then uses the borders to stretch the image the way I want. Works perfectly.
Now when taking my project over to Harmattan Meego. Which is using QtQuick 1.1 if I'm not mistaken the log tells me that:
@
Invalid property assignment: "sourceSize" is a read-only property
@Why has this changed? Is there some other way I'm supposed to use my SVGs with BorderImage that I'm not aware of?
-
Very strange as sourceSize is not a read-only property according to the documentation
http://library.developer.nokia.com/topic/MeeGo_1.2_Harmattan_API/html/qt4/qdeclarativeelements.html
-
Actually the documentation for Harmattan states this for the BorderImage element:
@
sourceSize : QSizeThis property holds the actual width and height of the loaded image.
In BorderImage, this property is read-only.
See also Image::sourceSize.
@But my question is why has this changed from previous versions of QtQuick?
It's not backwards compatible either (I cannot just write import QtQuick 1.0 and everything works as before).

[/quote]What is interesting is that for all read-only properties.. the documentation standard is something like this
@
sourceSize : QSize read-only
@Its confusing to see that its not followed though-out.

You could possibly look into using a "QDeclarativeImageProvider":http://doc.qt.nokia.com/4.7/qdeclarativeimageprovider.html to rasterize your SVGs to a given size that could then be scaled.

I'm wondering (pure speculation) if it wasn't so much of a recent introduction that it's read-only but rather it might have been designed to be read-only from the beginning, but was mistakenly allowed to be modified on Symbian.
I don't have the code or docs for both side-by-side at the moment, though. So, like I said, it's just a thought right now.
