Hello Sumit,
Thx for your reply, actually i only had this bug over IE. it is working over
FF.
the workaround was using JNSI which i really try to avoid when building my
modules.
public native JavaScriptObject getRange(Element element)/*-{
if(element.contentWindow.document.selection){
return element.contentWindow.document.selection.createRange();
}else {
return null;
}
}-*/;
public native void setSelection(JavaScriptObject selection)/*-{
var range = selection;
range.select();
}-*/;
i am keeping a reference of the Range JavaScript object when clicking on the
image icon to pop the dialogbox.
if(sender == colorChooser){
selection = getRange(richText.getElement());
kcp.setPopupPosition(sender.getOffsetWidth() +
sender.getAbsoluteLeft(), sender.getOffsetHeight() +
sender.getAbsoluteTop());
kcp.show();
}
when i am hiding the pop up i am using set Selection before setting the
color and it is working fine now.
public void onCellClicked(SourcesTableEvents sender, int row, int cell) {
String selectedValue = "#"+kcp.getColorsArr()[row][cell];
System.out.println("SELECTED COLOR="+selectedValue);
if(selection != null){
setSelection(selection);
}
basic.setForeColor(selectedValue);
//foreColors.setSelectedIndex(0);
kcp.hide();
}
this method is also implemented in the Inner Class EventListener which i
have made it implement TableListener
Thank you very much for your support.
regards,
ruds
