Thanks Vassilis, Craig for your responses, as I mentioned I am a
beginner with these things, I would like to put exact flow in my
application, maybe then I may get some specific help,
1. We have tool button- with name "Paste from excel" on click of it below
code gets called
protected Function pasteFromExcelFunction =new Function(){
public void execute(){
if(readOnly){
return;
}// its false
try{
if(pasteFromExcelHelper.pasteDataIntoGrid(BaseEditorGridPanel.this,
getRecordDef()));
doAfterPaste();
}
}
}
2. public boolean pasteDataIntoGrid(BaseEditorGridPanel grid,
BaseGridRecordDef recordDef)
{
boolean pasteSuccessful=true;
String pastedText= readFromClipboard(); // this method calls the
javascript code like below in point 3
//further code goes here
}
3 .private String readFromClipboard (){
return JavaScriptUtils.getClipboardData();
}
4.
public static native String getClipboardData()/*-{
i*f($wnd.clipboardData && clipboardData.setData){*
*return $wnd.clipboardData.getData('Text');*
}
So can you please suggest me the code change in above function point no.4
which will enable paste support with modern browsers, I am aware I am
asking very specific things, but I have constraints that I am not able to
debug as remote server where gwt code deployed needs some configuration and
code is using old version of GWT
Thanks.
