Hiding an APWidget ?

Android Processing

After some experimenting with APWidgets.....

I can hide an APWidgetContainer using the hide() method, but can't see/find a way to hide just one widget. I guess I could just have separate containers for each widget... but is there away to hide individual widgets in a container?
Rotating my tablet from landscape to portrait causes the APWidgetContainer.hide() function to 'undo'. Is there a way to prevent this so the so the widgets stay hidden?

Has anybody else found this and have ideas/solutions?

Many thanks

After some research...

Each APWidget has a View... the view has a public setVisible() method.
Basically, this code should hide the APWidget:

widget.getView().setVisible(false);

You could stop it from rotating in the first place using orientation() or from the manifest, or you can detect when the screen rotates and then call the function again, see getting the screen orientation...

Hello,

I'm trying to hide an apwidget textfield, and I'm having trouble getting it to work. My goal is to have an app that will connect via osc to a desktop computer, I want to be able to enter an ip adress and a port number for OSC connection.

I can use the .show() and .hide() function pretty easily but when I click the widget to enter a number, hide and show doesn't work anymore. I guess it's coming from focus that is taken from the widget and not given back afterwards.

Here's some code :

in my setup()

// text widget IP
ipContainer = new APWidgetContainer( this );
ipPhoneNumberField = new APEditText( myWidth/4, myHeight/2, myWidth/2, 100 );
ipContainer.addWidget(ipPhoneNumberField);
ipPhoneNumberField.setInputType(InputType.TYPE_CLASS_PHONE); //Set input type to numb keypad
ipPhoneNumberField.setImeOptions(EditorInfo.IME_ACTION_DONE); //Enables a Done button
ipPhoneNumberField.setCloseImeOnDone(true); //close the IME when done is pressed
// text widget Port
pPhoneNumberField = new APEditText( myWidth/4, myHeight*3/4, myWidth/2, 100 );
ipContainer.addWidget(pPhoneNumberField);
pPhoneNumberField.setInputType(InputType.TYPE_CLASS_PHONE); //Set input type to numb keypad
pPhoneNumberField.setImeOptions(EditorInfo.IME_ACTION_DONE); //Enables a Done button
pPhoneNumberField.setCloseImeOnDone(true); //close the IME when done is pressed

then I've use a function to show/hide stuff when clicking the device's menu button :

public void keyPressed() {
if (keyCode == KeyEvent.KEYCODE_MENU ){
if (!menu){
menu = true;
ipContainer.show();
}
else {
menu = false;
ipContainer.hide();
}
}
}

if I use

.getView().setVisible(false);

I get an error (I'm in eclipse, so he won't let me compile), eclipse suggests to use setVisibility(int myInt) instead, I tried but it just doesn't show or hide anymore even without giving focus to the widget.

So I don't know how to solve this, does anyone has an idea how to show hide widget pressing the menu button ?

cheers

It looks like Google may have updated their APIs. See the View Reference.

Hi thanks for your answer

so you think I should use setVisibility ?

public void keyPressed() {
if (keyCode == KeyEvent.KEYCODE_MENU ){
if (!menu){
menu = true;
ipContainer.show();
ipPhoneNumberField .getView.setVisibility(0); // show it
pPhoneNumberField .getView.setVisibility(0);
}
else {
menu = false;
ipContainer.hide();
ipPhoneNumberField .getView.setVisibility(1); // hide it
pPhoneNumberField .getView.setVisibility(1);
}
}
}

I must have made a mistake because I had tried that and it doesn't work on my device.

I have another set of button drawn with the menu, and if the textField is frozen (ie won't go away) it's the same for my buttons.

My buttons are made of a class, with a display method, in the draw() loop I just use an if else statement on the boolean menu to call buttons.display(); But if the textField is frozen this doesn't work : the menu variable is not updated when I press the menu button on my device. This is what made me think of a focus issue since my keyPressed function doesn't seem to be called at all.
