Press and hold on a Surface pro touch screen

I don't think disabling RMB will enable mouse down events though. The double click will work as the OS knows from the first short click and the second "mouse down" that it is a double click that is intended.

Easy way to test is to create av vi with a few different boolean controls with different mechanisms, and then use an event structure to see how/when/if mouse down events are fired.

And I am sure there are countless spectators here wating for your results with bated breath.  😉

Took me a while but I tried my surface with all possible switches. It seems that no matter what mechanism button I use, the mouse down event is always fired on release. I also got a hold of a Hatteland touch panel which also responds the same.

Hello everyone,

Disabling RMB on itself will not do the trick, but is necessary to implement a work-around that shows the "wanted behavior".

On Windows 7 and my personal Touch Panel this (not so clean and unpolished) work-around provide a switch until released boolean control value (only focused on the right value).

If you would want to have correct/proper events linked to this fake Switch Until Released behavior, then it might be more useful to start using some intermediate User Events.

However, this might further complicate the UI part of the application.

Downside for this approach is of course that you would not be able to use the same UI Event Handling for non-touch panels.

This could incur in some dynamically selectable User Interface Event Handling depending on which kind of PC (TP or non TP) you're using

Hi, just found a solution - at least for a Elo touch screen (USB).

All though the touch screen works out of the box plugged in the USB, the Microsoft Windows driver is what causes this issue. We installed the Elo driver and used a setting called "Force Mouse = 1". The driver then installs the touch screen as a mouse, and now all the buttons works as they should 🙂

We did similar driver installation on two other brands of touch screens with same success.

All the machines where running windows10

I have same problem. had design Labview application and it works fine with mouse but when i installed in Touch CPU. it wouldn't work.

I installed eGalaxy Touch Driver on Windows 10 OS. then application all buttons works perfectly as i wish.
