Re: Re: Key Press php-gtk1

Brian - I've never had to deal with the repeat issue, but for the selected keys, I have two thoughts. You should be able to use the name keyvals of KEY_SHIFT_L and KEY_SHIFT_R. We did something similar for the tab keys a few years back. If not, what about the Function Keys, as in F1 or F12 ?? hth, Madeleine D. Brian Stumm wrote:

Thanks to Madeleine for pointing out my error, I can now detect key release as well as key press. But I now have a new problem and looking for any ideas anyone might have. I must choose two keys on the keyboard that cannot be pressed using only one hand. Most keys fall into the "auto repeat" category where while holding the key down for long periods it will repeat the "press" action. I'm sure you've all experienced the annoying beeping from a computer with a key that is stuck down for whatever reason. I decided I could use the two shift keys as my two handed solution, however both shift keys use the value 65505 and I cannot determine that both shift keys are depressed. Using a combination of ctrl and shift is out because you can press them both using only one hand. Is there a way to treat the two shift or ctrl keys separate? Is there a way to disable auto-repeat for the keyboard (temporarily) via php-gtk? Any other ideas? Thanks. On Mon, Feb 15, 2010 at 12:50 PM, Madeleine D. <chezmmd@gmail.com> wrote:

Brian - You need to add 'add-events', after the realize, as in: $alert_window->add_events(GDK_KEY_PRESS_MASK|GDK_KEY_RELEASE_MASK); The key press mask is probably not needed, but I always add it anyway. Madeleine D. Brian Stumm wrote:

    
Not sure if messages are going through or not but...

I've discovered the key-press-event and key-release-event and while key-press is working for me, the key-release does not seem to work. Here is a snippet from my code: $alert_window = &new GtkWindow(GTK_WINDOW_DIALOG); $alert_window->connect('delete-event', 'hide_window'); $alert_window->set_border_width(0); $alert_window->set_policy(0, 0, 0); $alert_window->set_title('Notice!'); $alert_window->set_name('AlertWindow'); $alert_window->set_usize(400,430); $alert_window->realize(); $alert_window->set_position(GTK_WIN_POS_CENTER); $alert_window->connect('key-press-event', 'onKeyPress'); $alert_window->connect('key-release-event', 'onKeyRelease'); -----------------8<--SNIP /***** ONKEYPRESS/RELEASE() *****/ function onKeyPress($widget, $event) { global $righthand, $lefthand; echo "Pressed: " . $event->keyval; return true; } function onKeyRelease($widget, $event) { global $righthand, $lefthand; echo "Released: " . $event->keyval; return true; } Key Press echo's Pressed and a value (numeric) but the key release does nothing. Am I doing something wrong? On Mon, Feb 15, 2010 at 6:01 AM, Brian Stumm <bstumm@energytechnologysystems.com> wrote:

      
First, I am still using php-gtk1. I'd like to make the move to v2 but

do not have the luxury right now. I am looking to detect when keys are pressed (and held down) in php-gtk version 1. This is for a "two hand, no tie down" safety feature on our machines. Access to our machines is made possible by lifting the top of the machine using air cylinders. The air cylinders are controlled via an electric valve. To lower the top I need to require the user to press two keys on opposite sides of the keyboard and keep them depressed until the top closes completely. If they release before the top closes completely the top should go back up. Is there a way I can monitor key press and key release in version 1 of php-gtk? -- Brian Stumm ETS Energy Technology Systems, Inc. http://EnergyTechnologySystems.com bstumm@EnergyTechnologySystems.com 509-276-2015 (PH) 509-276-2016 (FX)
