Function Documentation

void drag_pointer ( xcb_connection_t *  conn,
Client client,
xcb_button_press_event_t *  event,
xcb_window_t  confine_to,
border_t  border,
callback_t  callback,
void *  extra 
)

This function grabs your pointer and lets you drag stuff around (borders).

Every time you move your mouse, an XCB_MOTION_NOTIFY event will be received and the given callback will be called with the parameters specified (client, border on which the click originally was), the original rect of the client, the event and the new coordinates (x, y).

void floating_assign_to_workspace ( Client client,
Workspace new_workspace 
)

Removes the floating client from its workspace and attaches it to the new workspace.

This is centralized here because it may happen if you move it via keyboard and if you move it using your mouse.

int floating_border_click ( xcb_connection_t *  conn,
Client client,
xcb_button_press_event_t *  event 
)

Called whenever the user clicks on a border (not the titlebar!) of a floating window.

Determines on which border the user clicked and launches the drag_pointer function with the resize_callback.

Called when the user clicked on the titlebar of a floating window.

Calls the drag_pointer function with the drag_window callback

Here is the call graph for this function:

void floating_focus_direction ( xcb_connection_t *  conn,
Client currently_focused,

)

Changes focus in the given direction for floating clients.

Changing to the left/right means going to the previous/next floating client, changing to top/bottom means cycling through the Z-index.

Here is the call graph for this function:

void toggle_floating_mode ( xcb_connection_t *  conn,
Client client,
bool  automatic 
)

Enters floating mode for the given client.

Correctly takes care of the position/size (separately stored for tiling/floating mode) and repositions/resizes/redecorates the client.

If the automatic flag is set to true, this was an automatic update by a change of the window class from the application which can be overwritten by the user.
