Updating image of a Button

Hello everyone,

i have a problem and i hope that someone hier can help me :-)

I have a UIButton. Programmatically i can set the Butten Highlighted by saying

Code:

myButton.highlighted = YES;

for exampel. On display, the Button gets Highlighted.. all works fine. Now i call a method from a C++ class

Code:

@implementation myClass
- (void)visualizeEvent 
{
myButton.highlighted = YES;
}
@end

the Button would be set to highligted, no problem, but on display, the Button status does not change. Do have anyone a idea, what the problem is?

A little bit more information about my programm:

To call the visualizeEvent method from the c++ class:

Code:

#import "myClass.h"
class myCPlusPlusClass
{
void function();
void setMyClass(myClass* ptr) { classPtr = ptr; }

myClass* classPtr;
};


void myCPlusPlusClass::function()
{
[classPtr visualizeEven];
}

Thanks in advance!
have a nice week
