Greets - I'm building a from-scratch standalong gui with small
real-estate (800x480 5" touchscreen). Obviously I won't be able to have
the traditional "full featured" elements like SilverDragon, but that's
ok. What I do have is a tab-widget with 5 tabs that hold all of my
workflows, but there are a couple buttons that need to be on multiple
tabs, such as CycleStart, FeedHold, Lubrication Enabled, etc. The "easy"
way of solving this would be to have them on a section of the
MainWindow, outside of the tab-widget, however there are tabs where I do
*not* want those buttons, so this isn't a preference. I would like to
have for example a "Lubrication Enabled" button on tabs 1 and 3, and if
I click it on tab 1, its actions, including status are mirrored to the
same button on tab 3, and vice versa. The buttons I want to use in this
case are indicating buttons, since it lets me quite easily add nice
graphic icons for the applicable button states. HAL signals would of
course be what trigger the hardware.
What is the recommended way of slaving multiple buttons together? Just
HAL or just signals, or both?
Thanks,
TH.
