         lastError = error;
         emit q->error(error);

◆ isEmbedded()

bool QX11EmbedContainerPrivate::isEmbedded ( ) const

Returns whether or not the windows' embedded flag is set.

Warning: This function is not part of the public interface.

Definition at line 1189 of file qx11embed_x11.cpp.

 }

◆ moveInputToProxy()

void QX11EmbedContainerPrivate::moveInputToProxy ( )

Moves X11 keyboard input focus to the focusProxy, unless the focus is there already.

Warning: This function is not part of the public interface.

When X11 keyboard input focus is on the focusProxy, which is a child of the container and a sibling of the client, X11 keypresses and keyreleases will always go to the proxy and not to the client.

Definition at line 1825 of file qx11embed_x11.cpp.

     XSetInputFocus(q->x11Info().display(), focusProxy->internalWinId(), XRevertToParent, CurrentTime);
 }

◆ rejectClient()

void QX11EmbedContainerPrivate::rejectClient ( WId window )

Rejects a client window by reparenting it to the root window.

Warning: This function is not part of the public interface.

The client will receive a reparentnotify, and will most likely assume that the container has shut down. The XEmbed protocol does not define any way to reject a client window, but this is a clean way to do it.

Definition at line 1694 of file qx11embed_x11.cpp.

 }

◆ topLevelParentWinId()

WId QX11EmbedContainerPrivate::topLevelParentWinId ( ) const

Returns the parentWinId of the window.

Warning: This function is not part of the public interface.

Definition at line 1202 of file qx11embed_x11.cpp.
