thanks Ismael, it works.
I tried doing some development in c/c++, after working in java for some tim=

All you have to do is add the directory where libgtkjni-2.6.so is
located to your java.library.path. So in FC4, you would do:

Re: [Java-gnome-developer] TextView

[Thijs 'L. L. <la...@sa...>]

Heya Igor,

The data that is typd in the the TextView is stored in a TextBuffer, I=20
suggest you do this:

text =3D (TextView)libg.getWidget("My textview drawn in the glade");
TextBuffer buffer =3D text.getBuffer();
String data =3D buffer.getText(buffer.getStartIter, buffer.getEndIter, tr=
ue);

with this you get the data from the start till the end of the text view=20
with all the hidden chars (which is what the last param stands for.

Hope this will get you going,

Greets,

[Java-gnome-developer] TextView

[igor h. <igo...@ho...>]

Hello personal everything in...
my name is igor hiarley and it is a pleasure to do part of the list.

do I have a question to do, as I recover the data typed in a TextView? I am 
using Glade to create the screens. in my class Java in I did like this.

private TextView text;
LibGlade libg = new LibGlade ("........")
....
text = (TextView)libg.getWidget("My textview drawn in the glade");

Which done the method that I use to recover the data type by the user in 
TextView???

Does some other component that I can use in the place of the textView that 
supports multiple text lines exist???

Thank you!!!

Re: [Java-gnome-developer] TreeView mouse location (now TextView)

[Igor F. <if...@re...>]

Hi all,

I'm still banging my head on a variation of this problem. With the
TreeView I ended up creating a timer that would fire off after the mouse
handler was invoked, get the current selection and find what was clicked
on that way.

Now I'm having this problem with a TextView. However, if I right-click
on a TextView, the selection isn't changed. So my approach doesn't work.
The only plausible way I see of doing this is to map the mouse location
to a lineNum/offset in the TextView somehow. After digging through the
java docs for a while, I can't find anything appropriate. Does anyone
know of a way this can be accomplished?

Thanks,
Igor

I used to think that Thread.yield() did the trick, and it did in one
working example I had. 

But then I used the exact same code in a piece of production code, and
it *didn't* work - mouse movement (ie, a Gtk event) required. Grr.

I recalled a comment someone made on IRC, and in a flash of inspiration,
speculated that if a GtkTimer was running, maybe it awakening would
cause an event which would get the main loop to fire.

This seems to work.

Code snippet:

   Timer _ticker = null
   int INTERVAL = 50;
...
	_ticker = new Timer(INTERVAL, new Fireable() {
		private long	last;

		public boolean fire() {
			long now = System.currentTimeMillis();
			System.err.println("Timer fired. Elapsed " + (now - last) + ", compared to interval "+INTERVAL);
			last = now;
			return true;
		}
	});
	_ticker.start();


I know others have discussed the fundamental bug lurking down in the way
that CustomEvents is hooked into the main loop, but I don't off hand
know what that diagnosis is.

Re: [Java-gnome-developer] DataColumnObject problems

Here is a very simple test case, which shows what I was talking about in
the previous email. I just create a TreeStore with a single
DataColumnObject, I add a string to it, and try to get it back. Instead
I get null.

Did anyone else encounter this?

Re: [Java-gnome-developer] TreeModels and warnings

[Igor F. <if...@re...>]

Hi Andrew,

Thanks for the mail. I've attached a tarball of the code in the state
that it was at the time of my initial email. Since then I've changed my
code and it now works. What I had is a TreeStore, with 2 TreeFilters on
top of it, and another TreeFilter on top of one of the first ones. I've
removed this stacking of filters and that resolves the problem. However,
I don't know if stacking Filters is legal, but due to lack of any
contrary evidence I assume it should be.

In any case, what I found from my debugging is that it seems to be a
problem with this stacking of filters. What would happen is that while
the bottom filter (if you imagine them stacked up) is in its filter()
method, the top filter would get called in the middle, this caused some
problems, and hence the warnings I was getting. If anyone can make any
sense of it, I think it would be probably useful.

Thanks,
Igor

[Java-gnome-developer] DataColumnObject problems

[Igor F. <if...@re...>]

Hi,

I'm having a problem using DataColumnObjects. I have the following code:

___________________________________________
TreeIter storeIter = store.appendRow(null);

store.setValue(storeIter, referenceDataColumn, varRep);
Object obj = store.getValue(storeIter, referenceDataColumn);
System.out.println(obj);
___________________________________________

Here referenceDataColumn is an object of type DataColumnObject.

That's ok. Ordinarily there is a pretty high bar in the Open Source
world before releasing code, because we are afraid to be judged on our
pasta code. (I took over a month out from coding to write a configure
and Makefile scheme, just so others would be able to build my project).

But in this case, tracking down bugs in obscure corner cases of
java-gnome that have not previously been exercised is more important. So
if you can tarball your code in some manner, then others can try and
replicate the problem.

[Java-gnome-developer] Gnome applets in Java

Hello,

I'm new to java-gnome and this list.
I already played a bit around with the API and also wrote a little app.
Now I would like to turn it into a panel applet, but I don't have clue,

[Java-gnome-developer] TreeView mouse location

[Igor F. <if...@re...>]

Hi,

I'm trying to get context-sensitive popup menus to appear in a tree
view. I want to be able to figure out which row the mouse is over in my
popup handler method (which uses MouseListener). The problem is that I
can't find anything that will tell me the location of the mouse over the
TreeView, only the current selection, so if I click on anything other
than the currently selected item, this won't work. Is there any
convenient way I can extract this information?

Hi,

The official gtk tutorial shows the details of GtkTable and GtkBox 
widgets, so we called layout manager.

http://www.gtk.org/tutorial/ch-packingwidgets.html

IMHO, the combination of GtkTable and GtkBox is simple than 
GridBagLayout but powerful enough.

To make an easy approach for java-gnome, we need following tutorials:
- Using gtk layout manger for java programmer
- Using Gtk.TreeView for java programmer

I want to write them but I'm not a native speaker/writer.
I'll gladly review and translate if someone write them.

I'm having problem tracing this problem down, it seems that in my sample
program it doesn't happen, but happens in the real program. I must admit
that the program has somewhat a spaghetti structure since I am only
getting to know java-GNOME and GTK, so I'm experimenting with things and
add more and more on top.

The problem seems to occur even when references to the TreeModelFilter
are replaced with references to the TreeStore, only then it is harder to
produce. Can someone shed any light on what the error is supposed to
mean, and what it might be related to?

Thanks,
 Igor

Hi Ismael,

I have been trying to reproduce the problem, by constructing a simple
test case, unfortunately the simple test case doesn't show the problem,
only my not-so-simple program does :).
I'll try to get at the root.
