|
|
|
1353
|
|
|
1354 The position of this toolbar is specified in the function
|
|
|
1355 `default-toolbar-position'. If the corresponding position-specific
|
|
|
1356 toolbar (e.g. `top-toolbar' if `default-toolbar-position' is 'top)
|
|
|
1357 does not specify a toolbar in a particular domain (usually a window),
|
|
|
1358 then the value of `default-toolbar' in that domain, if any, will be
|
|
|
1359 used instead.
|
|
|
1360
|
|
|
1361 Note that the toolbar at any particular position will not be
|
|
|
1362 displayed unless its visibility flag is true and its thickness
|
|
|
1363 \(width or height, depending on orientation) is non-zero. The
|
|
|
1364 visibility is controlled by the specifiers `top-toolbar-visible-p',
|
|
|
1365 `bottom-toolbar-visible-p', `left-toolbar-visible-p', and
|
|
|
1366 `right-toolbar-visible-p', and the thickness is controlled by the
|
|
|
1367 specifiers `top-toolbar-height', `bottom-toolbar-height',
|
|
|
1368 `left-toolbar-width', and `right-toolbar-width'.
|
|
|
1369
|
|
|
1370 Note that one of the four visibility specifiers inherits from
|
|
|
1371 `default-toolbar-visibility' and one of the four thickness
|
|
|
1372 specifiers inherits from either `default-toolbar-width' or
|
|
|
1373 `default-toolbar-height' (depending on orientation), just
|
|
|
1374 like for the toolbar description specifiers (e.g. `top-toolbar')
|
|
|
1375 mentioned above.
|
|
|
1376
|
|
|
1377 Therefore, if you are setting `default-toolbar', you should control
|
|
|
1378 the visibility and thickness using `default-toolbar-visible-p',
|
|
|
1379 `default-toolbar-width', and `default-toolbar-height', rather than
|
|
|
1380 using position-specific specifiers. That way, you will get sane
|
|
|
1381 behavior if the user changes the default toolbar position.
|
|
|
1382
|
|
|
1383 The format of the instantiator for a toolbar is a list of
|
|
|
1384 toolbar-button-descriptors. Each toolbar-button-descriptor
|
|
|
1385 is a vector in one of the following formats:
|
|
|
1386
|
|
|
1387 [GLYPH-LIST FUNCTION ENABLED-P HELP] or
|
|
|
1388 [:style 2D-OR-3D] or
|
|
|
1389 [:style 2D-OR-3D :size WIDTH-OR-HEIGHT] or
|
|
|
1390 [:size WIDTH-OR-HEIGHT :style 2D-OR-3D]
|
|
|
1391
|
|
|
1392 Optionally, one of the toolbar-button-descriptors may be nil
|
|
|
1393 instead of a vector; this signifies the division between
|
|
|
1394 the toolbar buttons that are to be displayed flush-left,
|
|
|
1395 and the buttons to be displayed flush-right.
|
|
|
1396
|
|
|
1397 The first vector format above specifies a normal toolbar button;
|
|
|
1398 the others specify blank areas in the toolbar.
|
|
|
1399
|
|
|
1400 For the first vector format:
|
|
|
1401
|
|
|
1402 -- GLYPH-LIST should be a list of one to six glyphs (as created by
|
|
|
1403 `make-glyph') or a symbol whose value is such a list. The first
|
|
|
1404 glyph, which must be provided, is the glyph used to display the
|
|
|
1405 toolbar button when it is in the \"up\" (not pressed) state. The
|
|
|
1406 optional second glyph is for displaying the button when it is in
|
|
|
1407 the \"down\" (pressed) state. The optional third glyph is for when
|
|
|
1408 the button is disabled. The optional fourth, fifth and sixth glyphs
|
|
|
1409 are used to specify captioned versions for the up, down and disabled
|
|
|
1410 states respectively. The function `toolbar-make-button-list' is
|
|
|
1411 useful in creating these glyph lists. The specifier variable
|
|
|
1412 `toolbar-buttons-captioned-p' controls which glyphs are actually used.
|
|
|
1413
|
|
|
1414 -- Even if you do not provide separate down-state and disabled-state
|
|
|
1415 glyphs, the user will still get visual feedback to indicate which
|
|
|
1416 state the button is in. Buttons in the up-state are displayed
|
|
|
1417 with a shadowed border that gives a raised appearance to the
|
|
|
1418 button. Buttons in the down-state are displayed with shadows that
|
|
|
1419 give a recessed appearance. Buttons in the disabled state are
|
|
|
1420 displayed with no shadows, giving a 2-d effect.
|
|
|
1421
|
|
|
1422 -- If some of the toolbar glyphs are not provided, they inherit as follows:
|
|
|
1423
|
|
|
1424 UP: up
|
|
|
1425 DOWN: down -> up
|
|
|
1426 DISABLED: disabled -> up
|
|
|
1427 CAP-UP: cap-up -> up
|
|
|

1549 toolbar thickness specifier (e.g. `top-toolbar-height' if

|
|
1550 `default-toolbar-position' is 'top) does not specify a thickness in a
|
|
|
1551 particular domain (a window or a frame), then the value of
|
|
|
1552 `default-toolbar-height' or `default-toolbar-width' (depending on the
|
|
|
1553 toolbar orientation) in that domain, if any, will be used instead.
|
|
|
1554
|
|
|
1555 Note that `default-toolbar-height' is only used when
|
|
|
1556 `default-toolbar-position' is 'top or 'bottom, and `default-toolbar-width'
|
|
|
1557 is only used when `default-toolbar-position' is 'left or 'right.
|
|
|
1558
|
|
|
1559 Note that all of the position-specific toolbar thickness specifiers
|
|
|
1560 have a fallback value of zero when they do not correspond to the
|
|
|
1561 default toolbar. Therefore, you will have to set a non-zero thickness
|
|
|
1562 value if you want a position-specific toolbar to be displayed.
|
|
|
1563
|
|
|
1564 Internally, toolbar thickness specifiers are instantiated in both
|
|
|
1565 window and frame domains, for different purposes. The value in the
|
|
|
1566 domain of a frame's selected window specifies the actual toolbar
|
|
|
1567 thickness that you will see in that frame. The value in the domain of
|
|
|
1568 a frame itself specifies the toolbar thickness that is used in frame
|
|
|
1569 geometry calculations.
|
|
|
1570
|
|
|
1571 Thus, for example, if you set the frame width to 80 characters and the
|
|
|
1572 left toolbar width for that frame to 68 pixels, then the frame will
|
|
|
1573 be sized to fit 80 characters plus a 68-pixel left toolbar. If you
|
|
|
1574 then set the left toolbar width to 0 for a particular buffer (or if
|
|
|
1575 that buffer does not specify a left toolbar or has a nil value
|
|
|
1576 specified for `left-toolbar-visible-p'), you will find that, when
|
|
|
1577 that buffer is displayed in the selected window, the window will have
|
|
|
1578 a width of 86 or 87 characters -- the frame is sized for a 68-pixel
|
|
|
1579 left toolbar but the selected window specifies that the left toolbar
|
|
|
1580 is not visible, so it is expanded to take up the slack.
