Hello,
I’m new to the list and this is my first post. I’ve taken over a
gtkmm project from a previous person. I’ve read through the
documentation and am fairly familiar with the GUI, but am by no means an
expert.
My situation is this:
I have an application where the user uses external hardware to change a channel
value. The hardware is a slider which can change the value from something like
0% to 100%. Right now, this channel level (i.e. 25%) is displayed in a text
box. There are many channel values that can be changed.
I would like to be able to use a touch screen to “click
and drag” across the channels on the GUI, thus being able to select
multiple channels. After selecting those channels, I would like to (either by a
hardware slider or maybe a software slider) change the values of those channels
“simultaneously” by moving 1 slider.
My question is this:
Is there a widget other than the text entries that I am currently using to
display the channel levels that will allow me to select everything with a click
and drag approach? Right now when I click and drag, I can only do so within
the text entry, not across multiple text entries.
Thanks,
Aaron Geier
