QDict

[fruzzo]

HI...I have a problem with the management of a QDict.... in my gui i have to print some objects collected inside a QDict. All work fine until I try to remove one of the objects from the dictionary. I call myDictionary.remove(mykey) and the object was removed well from the gui but when I make a refresh of the gui, the same object that I've just removed reappear...why?

Could you show the relevant code?

Ok...sorry, this one is the part of code about insert the symbol on a map and it works fine:

DtTMApplication::app()->ModelDataDict().setAutoDelete(false);
QString izKey ("ImpactZone_");
 
DtVector izLocalPosition;
DtGeodeticCoord geodIZPosition;
geodIZPosition.setLat(lat);
geodIZPosition.setLon(lon);
geodIZPosition.setAlt(alt);
myCoordinateSystem->geodeticToLocal(geodIZPosition, izLocalPosition);
QPtrList<DtPoint> myPoints;
DtPoint impactZonePoint(izLocalPosition.x(), izLocalPosition.y(), izLocalPosition.z());
myPoints.append(&impactZonePoint);
DtEnvironmentalModelData* impactZone = DtTMApplication::app()->createObject("Target Point", myPoints);
DtTMApplication::app()->ModelDataDict().remove(impactZone->key().string());
impactZone->setKey( izKey + QString::number(identifier));
DtTMApplication::app()->ModelDataDict().insert(impactZone->key().string(),impactZone);
impactZone->setCanEdit(false);
impactZone->setLineWidth(1);
impactZone->setColor(QColor(255,0,0));
DtTMApplication::app()->ModelDataDict().setAutoDelete(true);

DtTMApplication::app()->ModelDataDict().setAutoDelete(false);
QString izKey ("ImpactZone_");
			
DtVector izLocalPosition;
DtGeodeticCoord geodIZPosition;
geodIZPosition.setLat(lat);
geodIZPosition.setLon(lon);
geodIZPosition.setAlt(alt);
myCoordinateSystem->geodeticToLocal(geodIZPosition, izLocalPosition);
QPtrList<DtPoint> myPoints;
DtPoint impactZonePoint(izLocalPosition.x(), izLocalPosition.y(), izLocalPosition.z());
myPoints.append(&impactZonePoint);
DtEnvironmentalModelData* impactZone = DtTMApplication::app()->createObject("Target Point", myPoints);
DtTMApplication::app()->ModelDataDict().remove(impactZone->key().string());
impactZone->setKey( izKey + QString::number(identifier));
DtTMApplication::app()->ModelDataDict().insert(impactZone->key().string(),impactZone);
impactZone->setCanEdit(false);
impactZone->setLineWidth(1);
impactZone->setColor(QColor(255,0,0));
DtTMApplication::app()->ModelDataDict().setAutoDelete(true);

To copy to clipboard, switch view to plain text mode 

instead this one is the part about remove the symbol from the map:

QString izKey ("ImpactZone_");
DtTMApplication::app()->ModelDataDict().remove(izKey+QString::number(identifier));

QString izKey ("ImpactZone_");
DtTMApplication::app()->ModelDataDict().remove(izKey+QString::number(identifier));

To copy to clipboard, switch view to plain text mode

How do you "refresh" your gui?

How do you "refresh" your gui?

the library for the map do it automatically, so when a remove the symbol from dictionary it disappear automatically from the map too...when i zoom in/out or pan the map it reappear, and I don't want this behavior!

[wysota]

Can we see the code used to perform the refresh?

Can we see the code used to perform the refresh?

sorry but that libraries aren't open source...so I don't have too the code used to perform the refresh

May be a problem related to the QDict autodelete?

We can't help you then.

May be a problem related to the QDict autodelete?

No idea. I don't think this is a Qt related problem. I suggest you ask your closed source solution provider for help, we can't debug code we don't have access to.

ok ... anyway thanks!
