XkbGetDeviceButtonActions − Query the button actions associated with an X Input Extension device
|
Status XkbGetDeviceButtonActions |
(Display *dpy, XkbDeviceInfoPtr |
device_info, Bool all_buttons, unsigned int first_button, unsigned int num_buttons);
|
− dpy |
connection to X server |
− device_info
structure to update with results
− all_buttons
True => get information for all buttons
− first_button
number of first button for which info is desired
− num_buttons
number of buttons for which info is desired
XkbGetDeviceButtonActions queries the server for the desired button information for the device indicated by the device_spec field of device_info and waits for a reply. If successful, XkbGetDeviceButtonActions backfills the button actions (btn_acts field of device_info) for only the requested buttons, updates the name, type, supported, and unsupported fields, and returns Success.
all_buttons, first_button and num_buttons specify the device buttons for which actions should be returned. Setting all_buttons to True requests actions for all device buttons; if all_buttons is False, first_button and num_buttons specify a range of buttons for which actions are requested.
If a compatible version of Xkb is not available in the server or the Xkb extension has not been properly initialized, XkbGetDeviceButtonActions returns BadAccess. If allocation errors occur, a BadAlloc status is returned. If the specified device (device_info->device_spec) is invalid, a BadKeyboard status is returned. If the device has no buttons, a BadMatch status is returned. If first_button and num_buttons specify illegal buttons, a BadValue status is returned.
