keyListener "escape" and "enter".
I have a few buttons on a global popupscreen. The first time I found [ENTER] works but [ESC] cannot close the anti-pop. So I add
public boolean keyChar(char key, int status, int time) { //intercept the ESC key - exit the app on its receipt if (key == Characters.ESCAPE) close(); return false; }
to close the anti-pop and it works well. But after that [ENTER] may not work. I don't know how to do so that he can still come back to listen to the rating. The full code is as follows:
final class pScreen extends PopupScreen implements KeyListener { public pScreen() { ... class addlistener implements FieldChangeListener { ... } class addlistener2 implements FieldChangeListener { ... } myButton.setChangeListener(new addlistener()); myButton2.setChangeListener(new addlistener2()); } public void close() { UiApplication.getUiApplication().popScreen(this); } public boolean keyChar(char key, int status, int time) { if (key == Characters.ESCAPE) close(); if (key == Characters.ENTER) // How to do here so that I can still listen my buttons? return false; }
All aid should be assessed.
Fix your code as follows:
public boolean keyChar(char key, int status, int time) { //intercept the ESC key - exit the app on its receipt if (key == Characters.ESCAPE) close(); return super.keyChar(key, status, time); }

Satellite Pro L300 - Tab key and enter key nothing
I can't do some of my key to work - the tab key and enter key just won't do anything. Someone suggested turning NUMLOCK on, but this doesn't seem to work!
Any suggestions?
The model is sitting Pro L300.
Thank you.Hello
The tab key works also if the number lock is enabled so I think that the two keys simply do not work.
Have you tried an external keyboard on your laptop?If the external keyboard works, I think that your internal keyboard needs to be replaced. Go to a local authorized service provider. Technicians can order the right keyboard and Exchange you it.

Printer all in one HP3520 - how to select the wireless network and enter the WEP key?
According to print my wireless network is detected.
How to connect the! @# % printer $ fo the wireless network and enter the WEP key?
Instructions on the HP site tell me to selet NETWORK on the printer control panel. Well, there's a way to select the NETWORK from the control panel. It is not an option for him.
I downnloaded and installed the latest drivers.
I have restored the default settings.
How to select the wireless network and enter the WEP key?
All of HP's instructions seem to be for a newer printer with a touchscreen.
I want that the printer is connected to my main computer via the USB port. I want to be able to print wireless phones and tablets.
My 3520 is not a 'touch Screen' and it has wifi.
However, the following work:
Try to open the HP Deskjet 3520 icon, open the utilities tab, click on convert USB wireless, by following the steps on the screen.
This leads me to believe that ONLY the wireless doesn't work. I know now that the part of the sentence "Convert USB to wireless connection" is supposed to mean "works like USB and wireless.
Thank you for your help
