I am trying to use the the set label command: and I am having weird problems. something like this works: puObject->setLabel( "label" ); this fails: char txt[ PUSTRING_MAX ]; ... //kp slider kp_slider = new puSlider ( 100, 60, 200, TRUE ); kp_slider->setMinValue( GAIN_MIN ); kp_slider->setMaxValue( GAIN_MAX ); kp_slider->setValue( ( float ) aileron_pid->get_kp() ); //set value to aileron gains since roll is selected by default sprintf( txt, "Kp: %.3f", aileron_pid->get_kp() ); //format label kp_slider->setLabel( txt ); the label comes out like: *****>*****0****** ***** but I can make it work by adding an unused variable?! this works: //unused variable bbb char bbb[ PUSTRING_MAX ]; //if I remove this setLabel() fails! char txt[ PUSTRING_MAX ]; ... //kp slider kp_slider = new puSlider ( 100, 60, 200, TRUE ); kp_slider->setMinValue( GAIN_MIN ); kp_slider->setMaxValue( GAIN_MAX ); kp_slider->setValue( ( float ) aileron_pid->get_kp() ); //set value to aileron gains since roll is selected by default sprintf( txt, "Kp: %.3f", aileron_pid->get_kp() ); //format label kp_slider->setLabel( txt ); I also cannot set the label in the callback function. Please help. Cory |

I am ok with public code on this one. I put the GPL stuff on top of
the file. Here is the email I sent to John:
Wow! Fantastic response time! Thank you. I have been banging my head
on this problem for while now.
I attached the main file that I am working with.
The relevant bits(to the best of my knowledge) are located in the
following functions:
main: line 96
init_pui_widgets: line 453
pui_callback: line 516
I am doing the development in Ubuntu. I will send you the supporting
classes for this program if needed.
Let me know if you still want me to make a small sample program to
demonstrate the issue.
Also the char array for radio button labels:
char *controller_selector_labels[] = { "Roll", "Pitch", NULL };
gives a warning: softSim.cxx:76: warning: deprecated conversion from
string constant to 'char*'
Do you know how to fix that?
Thanks,
Cory

Hi,
this won't work, because txt is only allocated on the stack (local
variable), and it will be destroyed at the end of the function.
Introducing bbb cures the problem because it pushes txt further down
on the stack, thus avoiding that it is overwritten by the rest of
your code. If you introduce another function that uses more stack
space, chances are that the above code won't work anymore.
puObject::setLabel() does not copy the string; it just copies the
pointer to the string. Therefore you have to provide a buffer
that doesn't go out of scope as long as your widget exists.
Kind regards,
Jan R.
