Exemple #1

Fichier : QvisScreenPositioner.C Projet : HarinarayanKrishnan/VisIt28RC_Trunk

void
QvisScreenPositioner::sendNewScreenPosition()
{
    if((xPosition != xTempPosition) || (yPosition != yTempPosition))
    {
        xPosition = xTempPosition;
        yPosition = yTempPosition;

        update();

        emit screenPositionChanged(xPosition, yPosition);

        double xp = double(xPosition) / double(xScreenSize);
        double yp = double(yPosition) / double(yScreenSize);
        emit screenPositionChanged(xp, yp);
    }
}

Exemple #2

void

{
    screenX = x;
    screenY = y;
    updateText(screenX, screenY);
    closePopup();

    emit screenPositionChanged(screenX, screenY);
}
