What does queryCommandValue(“FontSize”) return?

Question

I am trying to get the font size of selected range in a html document. I used queryCommandValue to get it. Some times it return an integer. And some times it is not. I don't know what is it.

And I also tried another way to get the fontsize by getting the parent emlement's style. But it's not always correct for there could be different font size in its children.

Answer 1

This method returns a value between 1 and 7, for font sizes from "small" to "large", like in GMail.

If you want to get a font size in points or pixels, use

mshtml.IHTMLTxtRange range = _dom.selection.createRange() as mshtml.IHTMLTxtRange;
if (range != null)
{
   mshtml.IHTMLElement2 elem = range.parentElement() as mshtml.IHTMLElement2;
   fontSize.Text = elem.currentStyle.fontSize.ToString()
}
