Actually the

gtk_notebook_insert_page(blah, blah, blah)

was complaining that the
widget->parent
was NOT nil. The procedure evidiently calls gtk_widget_set_parent inside the gtk_notebook_insert_page. The gtk_widget_set_parent claims that the widget->parent was NOT nil and it should be so I set them to nil and I don't get the gtk error (in gtkobject.inc Procedure AddNBPage). However, I still don't see the notebook. I'm not sure what the issue is yet.

I'll update CVS with what I did so far.

Right now it looks like during the TNBPages.Insert, it sends a semdmessage3 and in the LM_ADDPAGE, it is complaining that the parent widget = nil.

I'm still looking into it though.

OK, I will fix the example so it is correct and see if things start showing up again.

I will also take a to see if it is correct.

Very interesting. How were you able to determine this? When I got the

error, it

kept giving me all kinds of strange GTK errors, but I don't remember any of them saying anything about the parent being nil. Instead, I received errors

like

the following: Gtk-CRITICAL **: file gtkfixed.c: line 176 (gtk_fixed_move): assertion

`widget

!= NULL' failed. Gtk-CRITICAL **: file gtkwidget.c: line 3731 (gtk_widget_set_usize):

assertion

`widget != NULL' failed. Is this the same error messages you were getting? And if so, how were you

able

to determine that it was complaining about the "parent" not being null? I

see

it is complaining about "widget != NULL", but that doesn't tell me it is

the

parent it is having a problem with. So how were you able to determine that?

Those are NOT the errors I was getting. I was actually getting the error Gtk-CRITICAL **: file gtksomething.c: line ??? (gtk_parent_set): assertion `widget == NULL' failed.

I wish I could figure out GDB because it seems to be very helpful to people

who

know it. But I can't seem to be able to figure out how to use it with FPC

to

help me debug things. I just don't understand how to use it for some

reason. It

just isn't clicking. Does anyone know of any good tutorials or anything to

help

me figure out how to use GDB to debug my FPC code?

I don't use gdb either because I never looked at it to see if it was easy or not. I just don't know how to use it either.

Oh, that is excellent that you figured out that error. I know it has been getting that error for a while now, but I hadn't had time to track it down. So it sounds like you got it fixed. Thank you.

I really appreciate your help with looking into these problems with notebook. It is a huge help to me.

Well, I figured out that problem, but it still doesn't display the notebook. Can you rewrite your exampl,e in the examples directory. It appears to me that all the relevent code is commented out and that causes the example to crash.

I mujst be mmissing something yet because it's still not appearing. Look at my MIAN.PP code, in the FormCreate and tell me if I am using the notebook correctly.

I already got an answer from Jean. He can't work on lazarus for some time because of a computer crash and has also lost some of his lazarus work.

Since he offered me to send the basic code for TBitMap and some other componets I'll try to integrate that stuff. Hope I can do it round about weekend.

bye,

Stefan

I just send a private email to Jean to ask about that. If he won't answer or no longer wants to maintain that code I can contribute some code to read any kind of bitmap.

I have a first version ready now but can't commit before tomorrow.

Current status is:

- You can load a bitmap
- you can display a bitmap but it's not displayed with the right colors

Q: Does anybody know anything about this? Since I don't know too much about GTK/X color scheme I have no idea what happens there. Could this be the result of different PUT-modes of the GTK put_pixel function? (I currently use it as introduced in gtkobject by Shane)

- My example sometimes dumps core. This seems to happen whenever the bitmap's size is greater than the current window size.

Q: How can I check the size of the actual window? (This should be done in the SetPixel function in gtkobject.inc)

bye,

Stefan

I am sure we can figure out the color thing... Cannot wait to see it.

Thanks for this nice feedback. Sorry to tell you that I spend this evening in a pub (aeehh, restaurant;-) instad of working on lazarus:-(.

A few minutes ago I took another quick look at the code and decided to wait with the 1st release for another 1 or 2 days. Mainly because I want to speed up/clean up things. Hope you can wait that long.

bye,

Stefan

That is ok I am working a little pub action tonight myself, I mean drinking my home brew stout while sitting behind the monitor.

Cheers
Cliff
