## Function Documentation

void edelib::netwm_callback_add | ( | NetwmCallback | cb,
|  | void * | data = `0`
| ) |  |

Register callback for events related to windows and environment. This function will open display by calling fl_open_display().

When actions get reported, window id will be set to target id. If action wasn't figured, it will be set to -1.

Note
  To get some events (e.g. NETWM_CHANGED_WINDOW_NAME) you will have to use XSelectInput() on source window.

void edelib::netwm_callback_remove | ( | NetwmCallback | cb | ) |

Remove callback if exists.

void edelib::netwm_window_close | ( | Window | win | ) |

Close window.

Window edelib::netwm_window_get_active | ( | void |  | ) |

Return ID of currently focused window. If fails, return -1.

int edelib::netwm_window_get_all_mapped | ( | Window ** | windows | ) |

Get array of mapped windows. Returns array size or -1 if fails. Call XFree() to free allocation.

bool edelib::netwm_window_get_all_states | ( | Window | win,
|  | list< NetwmStateValue > & | ret
| ) |  |

Get all window states. Returns false if wasn't able to retrieve window state.

Fl_RGB_Image* edelib::netwm_window_get_icon | ( | Window | win,
|  | unsigned int | requested_width = `0`
| ) |  |

Return window icon set with _NET_WM_ICON property. Since application can have multiple icons, with this function you can set desired size to be returned, via requested_width. If icon with requested size wasn't found, it will return the first one.

char* edelib::netwm_window_get_title | ( | Window | win | ) |

Return window title or NULL if fails. Call free() on returned string.

int edelib::netwm_window_get_type | ( | Window | win | ) |

Return window type by returning one of NETWM_WINDOW_TYPE_* codes. If fails, the function returns -1.

int edelib::netwm_window_get_workspace | ( | Window | win | ) |

Get workspace given window resides. If fails returns -2 or return -1 if window is sticky (present on all workspaces).

bool edelib::netwm_window_have_state | ( | Window | win,
|  | NetwmStateValue | val
| ) |  |

Check if window has given state. Returns false if not.

int edelib::netwm_window_is_manageable | ( | Window | win | ) |

Return 1 if given window is manageable (window can be moved or closed) or 0 if not. Desktop, dock and splash types are not manageable. In case it could not figure out this property, it will return -1.

void edelib::netwm_window_maximize | ( | Window | win | ) |

Maximize window.

Deprecated:
  with netwm_window_set_state().

void edelib::netwm_window_remove_strut | ( | Window | win | ) |

Remove offset, previously set with netwm_window_set_strut. If offset not set, it will do nothing.

void edelib::netwm_window_remove_strut_partial | ( | Window | win | ) |

Remove offset, previously set with netwm_window_set_strut_partial. If offset not set, it will do nothing.

void edelib::netwm_window_set_active | ( | Window | win,
|  | int | source = `0`
| ) |  |

Try to focus or raise given window. source must be set to 1 if request comes from application, and 2 when it comes from pager. By default, source is 0 so it (by specification) indicates using older specification version.

void edelib::netwm_window_set_state | ( | Window | win,
|  | NetwmStateValue | val,
|  | NetwmStateAction | action
| ) |  |

Set window state to one of NetwmStateValue values. Value will be set, removed or toggled according to NetwmStateAction action.

void edelib::netwm_window_set_strut | ( | Window | win,
|  | int | left,
|  | int | right,
|  | int | top,
|  | int | bottom
| ) |  |

Resize area by setting offsets to each side. win will be outside that area.

void edelib::netwm_window_set_strut_partial | ( | Window | win,
|  | int | sizes[12]
| ) |  |

Resize area by setting offsets to each side and win will be outside that area. This function will use newer _NET_WM_STRUT_PARTIAL hint, which is highly likely to be supported by newer window managers.

Array is in offset form: left, right, top, bottom, left_start_y, left_end_y, right_start_y, right_end_y, top_start_x, top_end_x, bottom_start_x, bottom_end_x.

void edelib::netwm_window_set_type | ( | Window | win,
|  | int | t
| ) |  |

Set window type by using one of NETWM_WINDOW_TYPE_* codes. Depending on window managers some types will be applied correctly when window is showed and for some, application must be restarted.

bool edelib::netwm_workarea_get_size | ( | int & | x,
|  | int & | y,
|  | int & | w,
|  | int & | h
| ) |  |

Get workarea set by window manager. Return false if fails.

void edelib::netwm_workspace_change | ( | int | n | ) |

Change current workspace.

void edelib::netwm_workspace_free_names | ( | char ** | names | ) |

Free allocated names array with netwm_workspace_get_names().

int edelib::netwm_workspace_get_count | ( | void |  | ) |

Return number of available workspaces. Returns -1 if failed to fetch workspaces count.

int edelib::netwm_workspace_get_current | ( | void |  | ) |

Currently visible workspace. Workspaces are starting from 0. Returns -1 if failed.

int edelib::netwm_workspace_get_names | ( | char **& | names | ) |

Get array of workspace names. Function returns number of allocated items in array and should be freed with netwm_workspace_free_names().

void edelib::wm_window_ede_restore | ( | Window | win | ) |

edewm specific: restore window to previous state

WmStateValue edelib::wm_window_get_state | ( | Window | win | ) |

Not part of NETWM. Set window state to one of WmStateValue.

void edelib::wm_window_set_state | ( | Window | win,
|  | WmStateValue | state
| ) |  |

Not part of NETWM. Get one of WmStateValue for given window.
