<div class="moz-cite-prefix">Hello,<br>
<br>
Last time I built GUI with Scilab, I did not find a comprehensive
website or book on the subject and resorted to a bunch of separate
sources (see Nikokay's answer).<br>
Here are a bunch of issues/tricks I learned by trial & error:<br>
<br>
- as for now, you cannot export uicontrols using the figure menu
or the "xs2svg, xs2png, ..." functions. It means that for example
if you put two frames side by side, one with buttons, the other
one with a plot (an axis), you'll get a blank image if you export
it. It's quite inconvenient when trying to build a documentation
with visual examples.<br>
<br>
- the documentation for gridbag layout constraint is just useless
(
<a class="moz-txt-link-freetext" href="https://help.scilab.org/docs/6.0.0/en_US/gridbag_constraints_properties.html">https://help.scilab.org/docs/6.0.0/en_US/gridbag_constraints_properties.html</a>
), but this layout is just the best in term of functionalities and
flexibility. It took me a lot of time to half understand how it
works, reading java documentations and trying to fill-in the gaps.<br>
<br>
- There is a nice trick to get a responsive GUI even if your
callback functions take some time to execute. The idea is, from
within the callback function, to first disable the callback
function of the uicontrol, run the long calculation and then
re-enable the callback. That way you avoid getting a huge amount
of events and callbacks that accumulate and lag behind the actions
of the user. As an example, imagine a slider where the callback
function runs a 500ms-long calculation and plot the results on a
graph. If you don't apply the trick described above, sliding the
slider can generate 10's of events in a fraction of a second and
then you have to wait for all the calculations and plotting to
finish in order to get back to a usable GUI.<br>
<br>
Hope it helps,<br>

<div dir="ltr">Hi Scilabers
<div><br>
</div>
<div>Is there a comprehensive manual or book (in English, or alt
German) about programming GUI in Scilab? (or a comprehensive
web-page)</div>
<div><br>
</div>
<div>I've found the Openeering one (18 pages):</div>
<div><a
href="http://www.openeering.com/sites/default/files/LHY_Tutorial_Gui.pdf"
moz-do-not-send="true">http://www.openeering.com/sites/default/files/LHY_Tutorial_Gui.pdf</a><br>
</div>
<div>... and I've looked at the help pages for uicontrol + run
some of the GUI demos in Scilab.</div>
<div><br>
</div>
<div>I have almost no background in GUI programming, nothing
successful anyway, but it could be nice if I could at least
get some basic GUI up running (e.g. a figure where one can
manage some controls on the left side + see the polar plot etc
on the right side).</div>
<div><br>
</div>
<div>I think that what I need is not just examples. I need
explanations, and preferably something coherent that I can
combine and work with, into something that works.</div>
<div><br>
</div>
<div>I've installed GUI builder from ATOMS. In the past I've
never been happy with programming on a high level. I prefer to
understand what goes on under the hood... so GUI builder is a
bit of a desperate grasp on my part.</div>
<div><br>
</div>
<div>Best regards,</div>
<div>Claus</div>
