Use of Slide bars

Use of Slide bars

 

1. Write the pre-declaration in the header file of the container:

   Class CAknSlider;

2. Define the CAknSlider pointer variable
   CAknSlider * iSlider;
3. Slide bar definition in Rss files
   

   Resource slider r_my_slider {layout = EAknFormSliderLayout3; minvalue = 0; maxvalue = 100; step = 1; valuetype = EAknSliderValueBareFigure; minlabel = "0"; maxlabel = "100 "; }

4. Add references to the container code file:

   # Include <aknslider. h>

5. Create a slide in the code file
   

   Void CsliderContainer: ConstructL (const TRect & aRect) {create1_wl (); TResourceReader aReader; CEikonEnv: Static ()-> events (aReader, R_MY_SLIDER); iSlider = new (ELeave) CAknSlider; iSlider-> HandleResourceChange (changes); iSlider-> setcontainer1_wl (* this); iSlider-> ConstructFromResourceL (aReader); CleanupStack: PopAndDestroy (); // iSlider-> SetObserver (this); iSlider-> SetMaximumTextL (_ L ("max"); SetRect (aRect); ActivateL ();}

   Use ResourceReader to add the header file of barsread. h

6. Add button
   Add TKeyResponse OfferKeyEventL (const TKeyEvent & aKeyEvent, TEventCode aType); declared in the header file
   Add implementation methods in the code file
   

   TKeyResponse CsliderContainer: OfferKeyEventL (const TKeyEvent & aKeyEvent, TEventCode aType) {return iSlider-> OfferKeyEventL (aKeyEvent, aType );}
