The CCoeControl class is defined in coecntrl.h. For full documentation of CCoeControl, see The CCoeControl class. The following functions have been added to CCoeControl's API in EPOC Release 5.
void OverrideColorL(TInt aLogicalColor,TRgb aColor);
Applications that call this member function will not work correctly on a version of EPOC earlier than ER5.
This function allows a control to override a colour setting specified in the application's colour scheme.
This function does not change the application's colour scheme — it changes the colour mapping used in this control only.
|
TInt aLogicalColor |
The logical colour. Indicates which part of a control the physical colour maps to. The set of logical colours for an EIKON application are defined in the TEikLogicalColor enum in |
|
TRgb aColor |
The new physical colour to which the logical colour should be mapped. |
This function can only leave with KErrNoMemory.
TBool GetColor(TInt aLogicalColor,TRgb& aColor) const;
Applications that call this member function will not work correctly on a version of EPOC earlier than ER5.
This function retrieves the physical colour which has been mapped to the logical colour specified by a call to OverrideColorL(). If the logical colour specified has not been overriden, the aColor value is not changed.
|
TInt aLogicalColor |
The logical colour for which the corresponding physical colour will be retrieved. The set of logical colours for an EIKON application are defined in the TEikLogicalColor enum in |
|
TRgb& aColor |
On return, contains the physical colour which has been mapped to aLogicalColour by a call to OverrideColorL(). |
|
TBool |
ETrue if aLogicalColour has been overridden, EFalse otherwise. |
