You have to make calls (typically, indirectly) on the Entry's setValue: method
in order to update the displayed value.
#import <simtools.h>
#import <gui.h>
#import <objectbase/SwarmObject.h>
@interface Controller: SwarmObject
{
id entry1;
id entry2;
int intVar;
int unusedIntVar;
}
- createEnd;
- (void)describe: outputCharStream;
@end
@implementation Controller
- createEnd
{
id frame = [Frame create: [self getZone]];
[frame setWindowTitle: "MyFrame"];
entry1 = [Entry createParent: frame];
[entry1 linkVariableInt: &intVar];
[entry1 pack];
entry2 = [Entry createParent: frame];
[entry2 linkVariableInt: &unusedIntVar];
[entry2 pack];
return self;
}
- update
{
[entry1 setValue: [entry1 getValue]];
[entry2 setValue: [entry1 getValue]];
return self;
}
- (void)describe: outputCharStream
{
char buf[10];
sprintf (buf, "%d", intVar);
[outputCharStream catC: buf];
[outputCharStream catC: "\n"];
}
@end
int
main (int argc, const char **argv)
{
id controller;
initSwarm (argc, argv);
controller = [Controller create: globalZone];
while (1)
{
[controller update];
while (GUI_EVENT_ASYNC ()) {}
}
