Symbian CAknSettingItemList使用心得

8, 若Skin被禁止，CAknSliderSettingPage中的current value, min/max label看不见，原因是它们的颜色跟背景色相同。可以同过设置字体颜色来解决。

1) In CAnkSliderSettingItem derived class, override member function CreateSettingPageL() as below:

CAknSettingPage *CreateSettingPageL()

{

CMyAknSettingPage *settingPage = new (ELeave) CMyAknSettingPage(SettingPageResourceId(), InternalSliderValue());

settingPage->SetSettingTextL(SettingName());

return dynamic_cast settingPage;

}

2) Customize Setting page

class CMyAknSettingPage : public CAknSliderSettingPage

{

public:

CMyAknSettingPage(TInt aResourceId, TInt &aSliderValue) :

CAknSliderSettingPage(aResourceId, &aSliderValue)

{

}

void ConstructL()

{

CAknSliderSettingPage()::ConstructL();

SliderControl()->OverrideColor(EColorLabelText, KRgbBlack); //Set label text color

ActivateL()

}

void SizeChanged()

{

CAknSliderSettingPage:SizeChanged();

CAknSlider *slider = SliderControl();

if(slider)

{

slider->->OverrideColor(EColorLabelText, KRgbBlack); //Set label text color

slider->DrawNow();

}

}

}
