[Scilab-Dev] Problem while solving Bug#14709

[nikhil goel]

Hi Clément
I am sorry I had my mid semester examinations due to which I was unable to
work on this bug for a while.
I have a few questions-
Uicontrol.java- line 1231 - this function sets the string of all the
uicontrol styles.
 SwingScilabPushButton.java line 107 - Function SetText.
This function is implementing the LaTeX in pushbutton. If I remove this,
the latex string disappears and $/alpha$ appears.

When I try to use a similar function in Checkbox/RadioButton, the LaTeX
string appears but the white portion of the checkbox/radiobutton disappears.
 I am unable to understand what is causing the checkbox/radiobutton to
break.

Also in ScilabSwingPushButton.java setText function line 117. If i remove
this line/change the text inside it, the latex is still being implemented.
Does this mean this line is just updating the text?

If I remove majority of the code of ScilabSwingPushButton, the
PushButton/checkbox/radiobutton is still working, which means that most of
the code is setting properties of pushbutton/checkbox/radiobutton.

Draw function is the rendering function so removing it removes the entire
PushButton/checkbox/radiobutton.
But I am not able to find why the checkbox/radiobutton is breaking.
I am unable to understand what is rendering the white box of
checkbox/radiobutton.
Can you please help me figure this out?

Thanking you in anticipation
Nikhil
