Ok I found the solution. It is just because I didn’t know the output function I discovered few seconds ago on another page of your wonderful website.

Thanks a lot for your work!

Another question if I can permit :
Is it possible to do button with round corner easily?

Hi Yair,
What do you mean by Visible? I am a beginner with Guide; for me, the create function and then the opening function of the figure are called by Matlab when I run the gui with the Command Window. I try to add my lines (variable = findjobj(findobj(gcf, 'Tag', 'bouton11'); variable.setFlyOverAppearance(true);) in these functions before your answer and also in the create function of the button but there is always this flicker.
I feel i am not far from the solution but I have no more ideas.

I thank you in advance.

@Mathieu – try to run findjobj after your figure is made visible if you wish to avoid the flicker

Thanks for your post. It is very helpful!
I don’t know the java language but I try to modify a button of my GUI (using GUIDE) to a borderless button. So I tried to use the setBorder function with [] to signify empty borders, but it is not working. I succeeded using the Fly Over Appearance in the create function of my button, like this:

variable = findjobj(hObject);
variable.setFlyOverAppearance(true);

But when I open my GUI, this one opens, then is hidden by Matlab and re-appears after. It seems to be a double opening on the screen.
Do you know why?

@James – you can get the axes pixel positions via the properties described here. You should also take into consideration the DataAspectRatio and related properties, described here. Remember to ensure that the axes uses pixel Units, and also to take into account that the axes may possibly be a child of some figure container (e.g., uipanel, uitab etc.), which have their own pixel position vector. And yes – after you take all these into consideration the rest is just a simple affine transformation…

@James – I do not know any easy way to do it. You can place a property listener on the aforementioned axes properties, such that whenever these properties change, the invoked callback will update the button position accordingly.

@Joel – customization of uicontrol buttons, including the issue of changing or removing the border, was discussed here.
