Thanks I was busy doing something similar when i saw your message.
For people who may find this thread in the future, here's the code for different types of widgets that I have now gotten working.
Create the header file like above and in that file is where you will be storing your values. You'll need 2 functions for each widget 1 to set the value the other to fetch the value when you open the screen.
Flex buttons:
static int getButtonState(int buttonIndex)
{
int temp = button_states[buttonIndex];
return temp;
}
static void setButtonState(int buttonIndex, int buttonState)
{
button_states[buttonIndex] = buttonState;
}
This can be used like this:
void Screen2View::setupScreen()
{
Screen2ViewBase::setupScreen();
int temp = Persistance::getButtonState( 0 ); /* This matches with the correct button in the array */
*Button*.forceState(temp);
}
And to set the value use something like this in the callback:
int buttonState = ofBtn.getPressed();
if(buttonState == pressed){
Persistance::setButtonState(Button, pressed /* 1 */);
}
else
{
Persistance::setButtonState(Button, unpressed /* 0 */);
}
For sliders its easy as well, 2 functions you'll need:
static void setSpeedStatus ( int speed)
{
speed_status = speed;
}
static int getSpeedStatus()
{
return speed_status;
}
In the callback:
void Screen2View::speedUpdate(int value)
{
Persistance::setSpeedStatus(value);
}
In void Screen2View::setupScreen()
Use this:
int speed = Persistance::getSpeedStatus();
speedSlider.setValue(speed);
Radio buttons 2 functions again:
static void setRadioGroup1 (int selectedRadio){
radio_group1_status = selectedRadio;
}
static int getRadioGroup1 ( void )
{
return radio_group1_status;
}
private:
static int radio_group1_status;
In the callback:
Persistance::setRadioGroup2(0Button);
To set the value:
void Screen2View::setupScreen()
{
Screen2ViewBase::setupScreen();
int radioGroup1Button = Persistance::getRadioGroup1();
switch(radioGroup1Button)
{
case fwdButton:
Btn.setSelected(pressed);
break;
case revButton:
Btn.setSelected(pressed);
break;
case faultButton:
Btn.setSelected(pressed);
break;
}
One thing to remember for radio buttons, if a button has the value of 0 it will now be the default value unless you initialize the storage variable to another number
