You missed the list in your last reply. It is quoted below, and I've attached the file you sent me as well (table.txt). On Thu, Jan 31, 2013 at 4:54 PM, Ferdinand Ramirez < ramirez ferdinand yahoo com> wrote:
Attached is a working program with GtkEntry in the table. If you comment out line 21 and uncomment line 20 to use GtkTextView instead of GtkEntry, you will encounter the error I mentioned. Similarly, if you replace the gtk_widget_show_all on line 65 by gtk_widget_show, the error goes away but does not draw the table, only the outermost frame. In fact, doing gtk_widget_show for successive levels of children works until you reach the GtkTextView level. Am I invoking (in lines 73 to 75) the function to create the table in the correct manner from the thread? What you see in lines 71 and 72 are alternatives to invoking the function but those have identical results as well. -Ferdinand
I've found that this isn't related to threading, and seems to be a bug in TextView; my guess is embedding TextViews inside TextViews is somehow a bad idea. This error only effects Gtk+-2.0 (at least 2.24.13), and does not effect Gtk+3.0 (3.6.4) I have attached a more concise version of the program that produces the bug. I found that if you delay the show_all on the embedded TextViews to another g_idle_add, you don't get the error. I believe the code is valid, so if nobody else has a comment you might want to file a bug. I don't know if Gtk+2 gets bugfixes anymore though.. The error is: Gtk-WARNING **: gtktextview.c:4610: somehow some text lines were modified or scrolling occurred since the last validation of lines on the screen - may be a text widget bug. Gtk:ERROR:gtktextview.c:4611:gtk_text_view_paint: code should not be reached And the backtrace is: #0 0x00000030f9a35ba5 in raise () from /lib64/libc.so.6 #1 0x00000030f9a37358 in abort () from
