I created a test case but before filing an issue I have to point out what
follows. (You find the relevant code below)
The test app features a CEF BrowserComponent with some text inside.
Text lines are not so long horizontally to fill the view, so the right part
is empty.
Also the bottom part is empty because only a few text lines are in the HTML.
On the Android device:
I can click on text and I have the mousedown/mouseup sequence (events are
fired and callbacks are issued).
I can click on the empty part on the right and I have the
mousedown/mouseup sequence (events are fired and callbacks are issued).
If I click on the empty part on the bottom I have no callbacks.
If I long-press on the text the Android text-selection interface appears.
If I long-press on the empty part on the right no callbacks are issued
(this is the issue this thread is about but it is entwined with something
else, read on).
I remind that the empty part on the right is a DIV with the callbacks on it.
And the bottom part is really empty.
Sofor my app to work
-the text should not be selectable in the BrowserComponent because in my
app the long-press on any iFrame in the list is just for launching the
pop-up menu.
-the long-press events should be issued also on the text, if present in the
iFrames.
How to have those two specs satisfied?
It seems that there are two questions, one is maybe the simplest to solve,
the other is maybe a bug to file an issue about.
And the two are together, it seems.
(They are not seen in the simulator)
Regards
public void start() {
if(current != null){
current.show();
return;
}
Form hi = new Form("Hi World");
hi.setLayout(new BorderLayout());
hi.add(BorderLayout.NORTH,new Label("Hi World"));
BrowserComponent bc=new BrowserComponent();
bc.addWebEventListener("onLoad", new ActionListener() {
@Override
public void actionPerformed(ActionEvent evt) {
System.out.println("onload");
bc.addJSCallback("var div=document.getElementById('divId');" +
"callMouseDown =function(){callback.onSuccess('mousedown');};callMouseUp
=function(){callback.onSuccess('mouseup');};"+
"div.addEventListener('mousedown', function () {"+
"callMouseDown();"+
"});"+
"div.addEventListener('mouseup', function () {"+
"callMouseUp();"+
"});"
, new SuccessCallback<BrowserComponent.JSRef>() {
@Override
public void onSucess(BrowserComponent.JSRef value) {
System.out.println("webview callback value="+value.getValue());
}});
}
});
bc.setPage("<HTML><BODY><DIV id='divId'
><DIV>TEST</BR>TEST</BR>TEST</BR>TEST</BR>TEST</BR>TEST</BR>TEST</BR></DIV></DIV></BODY></HTML>","");
hi.add(BorderLayout.CENTER,bc);
hi.show();
}
