Re: $doc.selection is undefined in GWT
I've also been trying to work with selections in GWT and found this GWT extension: http://code.google.com/p/rocket-gwt/wiki/Selections It works with GWT 1.5, I don't know if it has been tested with GWT 1.6. I haven't used it myself Text selections seems like a fairly important thing, does anyone know why it is not built into GWT, or if it will be in GWT 2.0? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: $doc.selection is undefined in GWT
found the answer. FF uses $wnd.getSelection().getRangeAt(0) thanks for all the help. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: $doc.selection is undefined in GWT
Thanks for the clarification. I am sure I am close now. but still get
an error. my code is
private native Element getSelectedTextParent() /*-{
var range = null;
if($wnd.document.selection){
range = $wnd.document.selection.createRange();
} else if ($wnd.getSelection) {
range = $wnd.getSelection().createRange();
} else if ($wnd.document.getSelection) {
range = $wnd.document.getSelection().createRange();
}
return range.parentElement();
//return $doc.selection.createRange().parentElement();
}-*/;
I am getting $wnd.getSelection().createRange is not a function in
FireFox. it seems $wnd.getSelection() is ok, but can not createRange()?

I use the range to get the parent Element, range.parentElement();
originally (using $doc), I get back a div, now I am getting back the

document.selection does not seem to be equivalent to $doc.selection,
even though it removes the browser incompatibility.
any ideas?
Use script like this one:
public static native String getSelection() /*-{
var txt = '';
if ($wnd.getSelection) {
txt = $wnd.getSelection();
} else if ($wnd.document.getSelection) {
txt = $wnd.document.getSelection();
} else if ($wnd.document.selection) {
txt = $wnd.document.selection.createRange().text;
}
return txt;
}-*/;

When accessing the browser's window and document objects from JSNI,
you must reference them as $wnd and $doc, respectively. Your compiled
script runs in a nested frame, and $wnd and $doc are automatically
initialized to correctly refer to the host page's window and
document.
'document' above references the iframe's document where your code runs
(i.e. the *.cache.html).

Re: $doc.selection is undefined in GWT
Hi, Seems there is something strange going on with search - I answered your question and can't see the reply either! The $ before doc is due to GWT loading into an IFrame - GWT ensures that $doc points to the window's document object (you can read more on that in the JSNI documentation from GWT home page). You don't mention which operating system you use, but I believe document.selection.createRange() only works on IE and not other browsers, so I guess yuo are developing on Windows, which uses IE as hosted mode browser and then testing on other browsers in web mode. Just do a google search for cross-browser document.selection.createRange() to see how you would do it for Opera, Safari, Chrom, Firefox etc. //Adam On 4 Juni, 02:05, bhomass bhom...@gmail.com wrote: I have a native method which uses $doc.selection.createRange() I am not sure why the $ before doc.
