Hi Everyone,

        I am trying to create traffic signal window.

i have added 4 bitmap frame when i change color one frame it will reflect corresponding frame (red,green or yellow) .how to do please guide me to complete this.

Hello GuruRamesh,

possibly you are mixing two concepts: (1) selecting a frame from a multi-frame bitmap and (2) coloring an alpha-only bitmap.

So far I understood your application case, you can either create a multi-frame bitmap containing different images for the different light colors

or

You create a simple (single-frame) bitmap containing a single generic image of the traffic light in the alpha-only format. Then you can colorize the image at the runtime.

I hope it helps you further.

Hello GuruRamesh,

I'm sorry, but I don't understand what you mean with 'how to change color based on input color .please share it.'.

Concerning the usage of frames please see the section: Select the frame number of a multi-frame bitmap resource.

Thanks for the update.

     i have created one componet and i have enum for 3 signal color (red,yellow,green)

 trafsignal.signal_status=Application::signal_status.greenSignal;  //now green siganl is enabled   and it is show in last position.

trafsignal.signal_status=Application::signal_status.yellowsignall; //now yellow signal is enabled   and it is show in middle position

trafsignal.signal_status=Application::signal_status.redsignall; //now red signal is enabled   and it is show in first position

(redcolor  yellowcolor green color --my light order like this)

 

here green working fine but when i run yellowsignal-how to change object to middle position.

Hello GuruRamesh,

if the above code lines have the desired effect to change the signal color to green/yellow/red, then you will need to execute the right code line when your application runs in the corresponding signal state. Where you implement the code or how you trigger it, its depending on your application case.
