Hi, i am plotting robot position that i update with a while loop on a figure, but there is an issue. I cannot reduce the window. In fact, i can but at every new iteration the figure just come back on the foreground. Is there a solution to fix it ? Thank you, Baptiste.

You probably call the figure command on the figure handle during the loop: figure(3); figure(h); This brings an existing figure to foreground. Avoid this, and provide the handle directly to the plot() method to make sure the data is still plotted into the right figure.
Here is my while loop
while(self.ctrl.simulateur.simulationEnCours==1)
self.ctrl.simulateur.deplacementRobot();
self.dessinerSimulation();
self.dessinerReconstruction();
set(self.lblInfoEtape,'String',['Etape ',num2str(self.ctrl.getNumeroEtapeEnCours()),' sur ',num2str(self.ctrl.getTaillePattern()),' : ',self.ctrl.getDesignationEtapeEnCours()]);
set(self.lblTimerEtape,'String',['Timer étape : ',self.convertirIterationTemps(self.ctrl.getTimerEtapeEnCours())]);
set(self.lblTimerTotal,'String',['Timer total : ',self.convertirIterationTemps(self.ctrl.getTimerPattern())]);
set(self.lblForme,'String',['Forme : ',char(self.ctrl.simulateur.piscineReconstruite.forme)]);
set(self.lblProfil,'String',['Profil : ',char(self.ctrl.simulateur.piscineReconstruite.profil)]);
set(self.lblLongueur,'String',['Longueur : ',num2str(self.ctrl.simulateur.piscineReconstruite.longueur),' mm']);
set(self.lblLargeur,'String',['Largeur : ',num2str(self.ctrl.simulateur.piscineReconstruite.largeur),' mm']);
pause(0.01);
end
And here are the two function i called
function dessinerReconstruction(self)
if(~isempty(self.ctrl.simulateur.piscineReconstruite.piscine))
cla(self.axeReconstruction);
[f,v] = self.ctrl.simulateur.piscineReconstruite.piscine.getFacesVertices();
patch('Faces',f,'Vertices',v,...
'FaceColor', [0.8 0.8 1.0], ...
'EdgeColor', 'none', ...
'FaceLighting', 'gouraud', ...
'AmbientStrength', 0.30,...
'parent', self.axeReconstruction);
axes(self.axeReconstruction);
material('dull');
camlight('headlight');
set(self.axeReconstruction,'CameraPosition', [0 0 8000]);
end
function dessinerSimulation(self)
cla(self.axeSimulation);
%Dessin du robot
repRobot = self.ctrl.getRepresentationRobot();
vertexRobot = zeros(8,3);
for i=1:8
vertexRobot(i,:) = [repRobot(1,i) repRobot(2,i) repRobot(3,i)];
end
facesRobot = [1 2 4 3; 8 7 5 6; 1 2 6 5 ; 3 4 8 7 ; 4 2 6 8 ; 1 3 7 5];
patch('vertices',vertexRobot,...
'faces', facesRobot,...
'parent', self.axeSimulation,...
'edgecolor','w',...
'FaceLighting', 'none',...
'FaceColor', 'flat',...
'FaceVertexCData', [0 1 1 0 0.8 0.8;
0 1 1 0 0.8 0.8;
0 1 0 1 0.8 0.8]');
%Dessin de la piscine
[fPiscine,vPiscine] = self.ctrl.getFacesVerticesPiscine();
patch('Faces',fPiscine,'Vertices',vPiscine,...
'FaceColor', [0.8 0.8 1.0], ...
'EdgeColor', 'none', ...
'FaceLighting', 'gouraud', ...
'AmbientStrength', 0.30,...
'parent', self.axeSimulation);
axes(self.axeSimulation);
material('dull');
camlight('headlight');
hold on;
grid on;
xlabel(self.axeSimulation, 'X (mm)');
ylabel(self.axeSimulation, 'Y (mm)');
end

Both of your functions include the line
axes(self.axeSimulation);
This command makes 'self.axeSimulation' the current axes AND brings its parent figure into focus, which is why your figure is returning to the foreground. If you just want to set 'self.axeSimulation' as the current axes without bringing it into focus you can replace the call to 'axes' with a call to 'set' (where 'fig' is the handle to the parent figure of 'self.axeSimulation'):
set(fig, 'CurrentAxes', self.axeSimulation);

The 'CurrentAxes' property might be changed, during the code runs, when a user dares to click in the GUI. Better do not rely on the 'CurrentAxes', but define the 'Parent' property directly.
Unfortunately, material and camlight do not expect a Parent as input. Sigh.
