No redraw with wxt and 'noraise'

[Philipp K. J. <ja...@ie...>]

There is an interesting issue with the wxt terminal
(on Linux, at least):

When I set up my terminal with the 'noraise' flag:

	set t wxt noraise

Then the window is not raised after a plot command,
instead the focus stays with the console window (so
far, all is according to spec).

However, the window also does not receive a redraw
event so that the old plot continues to be shown.
The window is only redrawn (with the new plot) after 
the mouse pointer enters the wxt window (or the
window is raised).

My guess is that wxt does not generate a redraw
event until the window system (X11) sends an event
(souch as MOUSE_IN) to the window.

This does not seem to be a problem when using
the old x11 terminal.

I wonder whether anybody has seen this before?
Is this at all dependent on the window manager?
(I use IceWM.)

Best,

		Ph.

Hi Philipp,

I can understand where this may come from, but I have not been able to 
reproduce it on my machine...
The origin of the problem is that the calls to wxWidgets and GTK to 
redraw the plot are sent from gnuplot main thread, whereas the main 
graphic events loop runs in a secondary thread. So there are cases where 
calls made in gnuplot main thread are not really executed until the 
secondary thread is woken up by the arrival of another event. I have 
already had to fix such problems, for example to make 'set term wxt 
close' close the window immediately. _However_, I am not able to 
reproduce what you describe, i.e. the plot not being redrawn until a 
mouse event arrives. I have tried 4.2.2 and gnuplot CVS, with compiz, 
metacity and kde4's kwin as window managers. Could you try with another 
window manager such as one of those ? I have wxGTK 2.8.6, could you tell 
me what wxGTK version you have ?

Thank you,

Timothée

I see the same behavior as Philipp on my machine, using gnuplot 4.2.2, kwin=
=20
3.5.7 as window manager, and wxGTK 2.8.4.

I can also observer such a behaviour for "set term wx" ... only sometimes, 
not very reproducible ... just try a lot of "splot x", "splot 100*x", "splot 
y" commands with different time delay between entering these commands ... 
then sometimes the graph is not redrawn.

I cannot reproduce this behavior here, neither under KDE
nor under IceWM.

Neither can I reproduce it on the gnome desktop with WM 
metacity 2.20.0: the plot is redrawn immediately.

wxt not working in gnuplot 4.2

[seliv <sel...@ub...>]

I have another puzzle with wxt in gnuplot 4.2, which sets wxt terminal by
default.
When I plot something it shows the first plot in wxt window, but then it is
freezed, if I click on it, I see a message that window does not respond and
suggest to force quit. x11 and other terminals work good. I have Dell vostro
1510 with Linux ubuntu 8.04.
If you know the reason why wxt does not work, let me know please.
