Thank you Boris.
i tried getComputedStyle in C++ for each node of the DOM.
i'm surprised, i never get the background images (wich are declared in a css
style rule for "DIV" tags) nor the background color.
Here is my sample code:
"nsAutoString empty;
nsCOMPtr<nsIDOMCSSStyleDeclaration> computedStyle;
aDefaultCSSView->GetComputedStyle(aDomElement,
empty,getter_AddRefs(computedStyle));
nsCOMPtr<nsIDOMCSSValue> aCssValue;
computedStyle->GetPropertyCSSValue(NS_LITERAL_STRING("background-image"),get
ter_AddRefs(aCssValue));
primitiveValue = do_QueryInterface(aCssValue);
if (primitiveValue) {
primitiveValue->GetStringValue(bgStringValue);
if (!bgStringValue.Equals(NS_LITERAL_STRING("none"))) {
nsCOMPtr<nsIURI> bgUri;
NS_NewURI(getter_AddRefs(bgUri), bgStringValue);
}else {
// ALWAYS NONE !!!
}
}
//non-transparent background-color
computedStyle->GetPropertyCSSValue(NS_LITERAL_STRING("background-color"),get
ter_AddRefs(aCssValue));
primitiveValue = do_QueryInterface(aCssValue);
if (primitiveValue) {
primitiveValue->GetStringValue(bgStringValue);
if (bgStringValue.Equals(NS_LITERAL_STRING("transparent"))) {
//ALWAYS TRANSPARENT !!
}
}
Am i missing something ? is there any inheritance somewhere ?
Thanks.
