- gui with PostCallback - Method catch messages from a thread
and insert data in a datastructure. one datastructure for each connected device.
- searching for devices is started from the menu and done by the thread in the background
- new devices are simple messages with special headers and go the same way as all other messages too. thread put them in a queue, postcallback catch dem ....
- all devices are shown in a devicetree (works), but updating the layout of the tree, with showing all subelements is only done when the user work - move the mouse over the gui.
because of further activities/ features I want that the screen is updated whenever a message arrives which bear on data shown on the gui, but not when messages arrive which are for devices in the background.
Is it possible to do this with upp? Current it is not done ore the delay is so huge that I don't realized it.
