Detailed Description
Adaptor class providing a 1:1 mapping of the D-Bus interface 'org.freedesktop.Telepathy.Connection.Interface.ContactGroups'.
Member Function Documentation
bool Tp::Service::ConnectionInterfaceContactGroupsAdaptor::DisjointGroups | ( | ) | const |
Return the value of the exported D-Bus object property
DisjointGroups
of type bool
.Adaptees should export this property as a Qt property named 'disjointGroups' with type bool.
True if each contact can be in at most one group; false if each contact can be in many groups.
This property cannot change after the connection has moved to the Connected state. Until then, its value is undefined, and it may change at any time, without notification.
- Returns
- The value of exported property
DisjointGroups
.
uint Tp::Service::ConnectionInterfaceContactGroupsAdaptor::GroupStorage | ( | ) | const |
Return the value of the exported D-Bus object property
GroupStorage
of type uint
.Adaptees should export this property as a Qt property named 'groupStorage' with type uint.
Indicates the extent to which contacts' groups can be set and stored. This property cannot change after the connection has moved to the Connected state. Until then, its value is undefined, and it may change at any time, without notification.
- Returns
- The value of exported property
GroupStorage
.
QStringList Tp::Service::ConnectionInterfaceContactGroupsAdaptor::Groups | ( | ) | const |
Return the value of the exported D-Bus object property
Groups
of type QStringList
.Adaptees should export this property as a Qt property named 'groups' with type QStringList.
The names of all groups that currently exist. This may be a larger set than the union of all contacts'
groups
contact attributes, if the connection allows groups to be empty.Change notification is via GroupsCreated() and GroupsRemoved() ; clients can also distinguish between a create/remove pair and a renamed group by receiving GroupRenamed() .
This property's value is not meaningful until the ConnectionInterfaceContactListInterface::ContactListState has become Success.
- Returns
- The value of exported property
Groups

SetContactGroups
on this object.Adaptees should export this method as a Qt slot with the following signature: void setContactGroups(uint contact, const QStringList& groups, const Tp::Service::ConnectionInterfaceContactGroupsAdaptor::SetContactGroupsContextPtr &context);
Implementations should call MethodInvocationContext::setFinished (or setFinishedWithError accordingly) on the received context object once the method has finished processing.
New york new york casino roller coaster. Add the given contact to the given groups (creating new groups if necessary), and remove them from all other groups.
This is the easiest and most correct way to implement user interfaces that display a single contact with a list of groups, resulting in a user expectation that when they apply the changes, the contact's set of groups will become exactly what was displayed.
If the user is removed from a group of which they were the only member, the group MAY be removed automatically.
In protocols like XMPP where groups behave like tags, a group with no members has no protocol representation.
Any GroupsCreated() , GroupsChanged() and GroupsRemoved() signals that result from this method call MUST be emitted before the method returns.
This method SHOULD NOT be called until the ConnectionInterfaceContactListInterface::ContactListState changes to Success. If the ContactListState is Failure, this method SHOULD raise the same error as ConnectionInterfaceContactListInterface::GetContactListAttributes() .

If DisjointGroups is true, this will also remove each member from their previous group.

Add the given members to the given group, creating it if necessary.
If DisjointGroups is true, this will also remove each member from their previous group.

Somebody told me that they recently received a payout from Global Poker, so I put in my withdrawal request again and actually received that payout this time. It took a few days, but they approved it and sent it via. Youtube videos poker 2019. Detailed Global Poker Story So maybe you haven't been exposed to Global Poker but I have gone from loving this site to becoming quite the skeptic. First off, this is one of the only sites that works in the US and through quite a few comments and stories apparently actually pays out reliably in a.

Remove all members from the given group, then remove the group itself. If the group already does not exist, this method SHOULD return successfully.

Implementations should call MethodInvocationContext::setFinished (or setFinishedWithError accordingly) on the received context object once the method has finished processing.
Rename the given group.
On protocols where groups behave like tags, this is an API short-cut for adding all of the group's members to a group with the new name, then removing the old group.
Otherwise, clients can't perform this operation atomically, even if the connection could.
Any GroupRenamed() or GroupsRemoved() signals that result from this method call MUST be emitted before the method returns.
This method SHOULD NOT be called until the ConnectionInterfaceContactListInterface::ContactListState changes to Success. If the ContactListState is Failure, this method SHOULD raise the same error as ConnectionInterfaceContactListInterface::GetContactListAttributes() .

Introduction
Remember old X-Window call-back system? Generally it isn't type safe and flexible. There are many problems with them. Qt offer new event-handling system - signal-slot connections. Imagine alarm clock. When alarm is ringing, signal is sending (emitting). And you're handling it as a slot.
- Every QObject class may have as many signals of slots as you want.
- You can emit signal only from that class, where signal is.
- You can connect signal with another signal (make chains of signals);
- Every signal and slot can have unlimited count of connections with other.
- ATTENTION! You can't set default value in slot attributes. e.g.
void mySlot(int i = 0);
Qt Signal Slot Const Reference Guide
Connection
You can connect signal with this template:
QObject::connect ( const QObject * sender, const char * signal, const QObject * receiver, const char * method);
You have to wrap const char * signal and const char * method into SIGNAL () and SLOT() macros.And you also can disconnect signal-slot:
QObject::disconnect ( const QObject * sender, const char * signal, const QObject * receiver, const char * method);

Widgets emit signals when events occur. For example, a button will emit a 'clicked' signal when it is clicked. A developer can choose to connect to a signal by creating a function (a 'slot') and calling the
connect()
function to relate the signal to the slot. Qt's signals and slots mechanism does not require classes to have knowledge of each other, which makes it much easier to develop highly reusable classes. Since signals and slots are type-safe, type errors are reported as warnings and do not cause crashes to occur.For example, if a Quit button's
clicked()
signal is connected to the application's quit()
slot, a user's click on Quit makes the application terminate. In code, this is written asconnect(button, SIGNAL (clicked()), qApp, SLOT (quit()));
Connections can be added or removed at any time during the execution of a Qt application, they can be set up so that they are executed when a signal is emitted or queued for later execution, and they can be made between objects in different threads.
The signals and slots mechanism is implemented in standard C++. The implementation uses the C++ preprocessor and moc, the Meta-Object Compiler, included with Qt. Code generation is performed automatically by Qt's build system. Developers never have to edit or even look at the generated code.
