[B3G B3G]

I am trying to test NTextField in Xcode, i have already Implement a cn1-native-controls in my project and implementation has ben well done.  but, unfortunately the app crash while i trying to instantiate "NTextField". I extracted the generated source code & run it on Xcode this is the error log trace I got: (screen shot)

my code is :

         NTextField tf1 = new NTextField(TextField.PASSWORD);

            tf1.getAllStyles().setFont(Font.createTrueTypeFont(Font.NATIVE_MAIN_LIGHT, 15f));

            System.out.println("Finished setting font");

            tf1.getAllStyles().setFgColor(0x003300);

            tf1.getAllStyles().setBgTransparency(255);

            tf1.getAllStyles().setBgColor(0xcccccc);

            tf1.getAllStyles().setAlignment(CENTER);

Do you have any fix for this issue?

I've made a small change to guard against this scenario (where the style doesn't have a font defined).  You can get the updated cn1lib here https://github.com/shannah/cn1-native-controls/blob/master/bin/cn1-native-controls.cn1lib

Or wait until it is updated in Codename One settings and update there - should be within a few days.

I've posted my test case here (which works fine on iOS).

thank's Steve.

the application does not crash now, but the problem in the style that I defined is not taken into consideration, and the size(width) of TextField is very small as you see in screenshot

Try setting the font to one of the native fonts or other ttf font

I followed your example, by putting a native font.

My code :

       TableLayout t = new TableLayout(1, 2);
        final Container cntPin = new Container(t);
        final NTextField tfCodePin = new NTextField(TextField.PASSWORD);
        tfCodePin.getAllStyles().setFont(Font.createTrueTypeFont(Font.NATIVE_MAIN_LIGHT, 3f));
       
        tfCodePin.getAllStyles().setFgColor(0x003300);
        tfCodePin.getAllStyles().setBgTransparency(255);
        tfCodePin.getAllStyles().setBgColor(0xcccccc);

        cntPin.add(t.createConstraint().widthPercentage(50), lblPinCode);
        cntPin.add(t.createConstraint().widthPercentage(50), tfCodePin);

Do you have any fix for  my issue?

[B3G B3G]

Hi, 

I still have the same problem even if I took your example :

the code i tested is this one, and i also tried to setting the font to one of the native fonts or other ttf fon

My code :

       TableLayout t = new TableLayout(1, 2);
        final Container cntPin = new Container(t);
        final NTextField tfCodePin = new NTextField(TextField.PASSWORD);
        tfCodePin.getAllStyles().setFont(Font.createTrueTypeFont(Font.NATIVE_MAIN_LIGHT, 3f));
       
        tfCodePin.getAllStyles().setFgColor(0x003300);
        tfCodePin.getAllStyles().setBgTransparency(255);
        tfCodePin.getAllStyles().setBgColor(0xcccccc);

        cntPin.add(t.createConstraint().widthPercentage(50), lblPinCode);
        cntPin.add(t.createConstraint().widthPercentage(50), tfCodePin);

[Steve Hannah]

I copied and pasted your code into a sample app, and I don't get the same thing:

private void showTestForm2() {
        Form f = new Form("Test Form", new BorderLayout());

        TableLayout t = new TableLayout(1, 2);
        final Container cntPin = new Container(t);
        final NTextField tfCodePin = new NTextField(TextField.PASSWORD);
        tfCodePin.getAllStyles().setFont(Font.createTrueTypeFont(Font.NATIVE_MAIN_LIGHT, 3f));
       
        tfCodePin.getAllStyles().setFgColor(0x003300);
        tfCodePin.getAllStyles().setBgTransparency(255);
        tfCodePin.getAllStyles().setBgColor(0xcccccc);

        cntPin.add(t.createConstraint().widthPercentage(50), new Label("Pin Code"));
        cntPin.add(t.createConstraint().widthPercentage(50), tfCodePin);
        f.add(CENTER, cntPin);
        f.show();
    }
