Issue of the Implementation # S0572

Brief

Incorrect registration of the "start-index" property for AtkHyperlink

Detailed Description

The "start-index" property of AtkHyperlink is not registered correctly: PROP_END_INDEX identifier is used instead of PROP_START_INDEX. So if one tries to get the value of the property, the value of the "end-index" property will be returned instead.

Problem location(s) in the standard

ATK 1.9.0 Reference Manual, AtkHyperlink

Example

//Object MyAtkHyperlink, which derives from AtkHyperlink
//and implements its interfaces
guint my_atk_hyperlink_get_start_index(AtkHyperlink* link_)
{
    return 10;
}
guint my_atk_hyperlink_get_end_index(AtkHyperlink* link_)
{
    return 20;
}
//...
int main()
{
    AtkHyperlink* link = g_object_new(MY_TYPE_ATK_HYPERLINK, NULL);
    gint start_index = 0;
    g_object_get(link, "start-index", &start_index, NULL);
    //now start_index is 20, but should be 10
    return 0;
}

Possible solutions

It is required to fix installation of the "start-index" property in the atk_hyperlink_class_init() function:
