Sure thing. I wasn't sure which was most appropriate. I'm hesitant
about posting to this list because I do not wish to be seen as
styling myself a 'developer'; nor do I wish to add chaff and
annoying newbie errors to the list traffic. I'm recovering rusty old
ANSI-C programming skills from high school, and I have absolutely no
'real' programming experience.
In other words:
1) I am NOT a developer.
2) My code suggestions SHOULD be reviewed by actual developers before
implementation.
3) Tell me to go away if I'm bothering you.
C.B. is correct, of course, about how my 'fix' worked; it just
prevented the gtk_clist_moveto(). Removing the conditional execution
entirely does solve the jumping problem. However, this prevents
jumping when required, i.e., if 'jump to new search' is selected, and
the bottom of the search list is not visible.
1) Would the following substitution [which seems to work] be
acceptable? It seems to solve my problem.
-2297 if (!GTK_WIDGET_HAS_FOCUS(GTK_WIDGET(clist)))
gtk_clist_moveto(clist, row, 0, 0.0, 0.0);
+2297 if ( gtk_clist_row_is_visible(clist, row) !=
GTK_VISIBILITY_FULL)
gtk_clist_moveto(clist, row, 0, 0.0, 0.0);
2) What's going on with the "! GTK_WIDGET_HAS_FOCUS" conditional
"gtk_ctree_node_moveto()" functions in the following places? I tried
changing them into straight visibility tests as above, and then
finally tried removing them; nothing I did seemed to change the
behavior of the GUI in any way. I'm mainly just curious, but someone
might want to review them.
a) in "src/ui/gtk/gtk1/search.c":
2366 if (!GTK_WIDGET_HAS_FOCUS(GTK_WIDGET(ctree)))
gtk_ctree_node_moveto(ctree, node, 0, 0.0, 0.0);
b) in "src/ui/gtk/main_cb.c":
378 if (!GTK_WIDGET_HAS_FOCUS(GTK_WIDGET(ctree)))
gtk_ctree_node_moveto(ctree, node, 0, 0.0, 0.0);
The documentation makes it sound like gtk_ctree_node_is_visible(),
the closest analog to the function that worked for me above, cannot
guarantee that the node itself will actually be within the viewable
container bounds. As far as I can tell, it can't ... but I'm unsure
of whether I've actually seen the code change execute.
3) Most importantly (probably): has anyone else running with GTK
+1.2 on any other platform experienced problems with the 'jumping'
behavior? My GTK+ version is 1.2.10, and my X11 version is "1.1.3 -
XFree86 4.4.0".
