1447 Plist of default frame-creation properties for Gtk frames.
|
|

1448 These override what is specified in the resource database and in
|
|

1449 `default-frame-plist', but are overridden by the arguments to the

|

1450 particular call to `make-frame'.

1452 Note: In many cases, properties of a frame are available as specifiers

1453 instead of through the frame-properties mechanism.

1454
|
|
|
1455 Here is a list of recognized frame properties, other than those
|
|
|
1456 documented in `set-frame-properties' (they can be queried and
|
|
|
1457 set at any time, except as otherwise noted):

1458
|
|
|
1459 initially-unmapped If non-nil, the frame will not be visible
|
|
|
1460 when it is created. In this case, you
|
|
|
1461 need to call `make-frame-visible' to make
|
|
|
1462 the frame appear.
|
|
|
1463 popup If non-nil, it should be a frame, and this
|
|
|
1464 frame will be created as a "popup" frame
|
|
|
1465 whose parent is the given frame. This
|
|
|
1466 will make the window manager treat the
|
|
|
1467 frame as a dialog box, which may entail
|
|
|
1468 doing different things (e.g. not asking
|
|
|
1469 for positioning, and not iconifying
|
|
|
1470 separate from its parent).
|
|
|
1471 inter-line-space Not currently implemented.
|
|
|
1472 toolbar-shadow-thickness Thickness of toolbar shadows.
|
|
|
1473 background-toolbar-color Color of toolbar background.

1474 bottom-toolbar-shadow-color Color of bottom shadows on toolbars.
|
|
|
1475 (*Not* specific to the bottom-toolbar.)
|
|
|
1476 top-toolbar-shadow-color Color of top shadows on toolbars.

1477 (*Not* specific to the top-toolbar.)
|
|
|
1478 internal-border-width Width of internal border around text area.
|

1479 border-width Width of external border around text area.
|
|
|
1480 top Y position (in pixels) of the upper-left
|
|

1481 outermost corner of the frame (i.e. the
|
|
|
1482 upper-left of the window-manager
|
|
|
1483 decorations).

1484 left X position (in pixels) of the upper-left

1485 outermost corner of the frame (i.e. the
|
|
|
1486 upper-left of the window-manager
|
|
|
1487 decorations).

1488 border-color Color of external border around text area.
