+HOW TO MOVE A GUI-OBJECT:
+
+Select a gui-object , then navigate the object by using the
+4 direction-keys: UP , DOWN , LEFT or RIGHT.
+If you press the SHIFT-Key too , the object will move 10 times faster.
+
+
+PROPERTIES-DIALOG-WINDOW:
+
+"dimensions(pix): size:" = square-size of the gui-objects in pixels.
+"dimensions(pix)(pix): width: height:" = width & height of the rectangular
+ gui-object in pixels.
+"selectable dimensions(pix): size:" = square-size of the selectable top-left
+ corner of my_canvas in pixels.
+"flash-time(ms)(ms): hold:" = flash-hold-time in msec = duration of activity,
+ if a bang-object was activated by any message-event
+ or by a mouse-click.
+"flash-time(ms)(ms): intrrpt:" = flash-interrupt-time in msec = duration
+ of inactivity , if an already activated bang is activated
+ once more.
+"output-range: left: right:" = hslider-bounds for input- as well as
+ output-values.
+"output-range: bottom: top:" = vslider-bounds for input- as well as
+ output-values.
+"non-zero-value: value:" = toggle has 2 value-states: zero and this value.
+"visible_rectangle(pix)(pix): width: height:" = width & height of a visible,
+ deactivated rectangle in pixels.
+"init" or "no init" = if "init"-mode is selected , the object displays and puts
+ out its previously saved value.
+ if "no init"-mode is selected, nothing will happen.
+"new&old" or "new-only" = the radiobutton-object changes its state in 2 ways:
+ "new&old"-mode: output sends previous state off, current state on;
+ "new-only"-mode: output sends only current state on.
+"number:" = number of buttons of a radiobutton.
+"steady on click" or "jump on click" = the 2 slider-objects
+ react to mouse-click in 2 ways:
+ "steady on click"-mode: slider-knob stays in position,
+ mouse and knob will move parallel;
+ "jump on click"-mode: slider-knob jumps immediately to new
+ mouse-position, positions of mouse and knob will be identical.
+"send-symbol:" = an output-message can be received by a receive-object
+ with the same send-symbol-name.
+"receive-symbol:" = a send-object with the same symbol-name can send
+ an input-message to the gui-object.
+"label: name:" = visible name of a gui-object; it will be moved together with
+ the gui-object.
+"label: x_off: y_off:" = coordinates of the label in relation to top-left
+ corner of gui-object.
+"label: font: fontsize:" = font-properties of label.
+"colors:" = a click on radiobuttons "background:", "front-color:" or
+ "label-color:" activates the color-fields on the right side
+ which display the current color of the item;
+ to select a different color, click on one of the 30 small
+ preset-color-buttons;
+ each color (background, front, label) can be tuned by its
+ RGB-values (0 .. 252, step 4) and a click on the set-buttons.
+
+
+THE DOLLAR-THING:
+
+if you want to send to, or to receive from gui-objects in abstractions,
+ you have to write into the property-entry:
+ #1-label (instead of $1-label).
+
+if you want a unique send-receive-symbolname:
+ type #0-uniquelabel (instead of $0-uniquelabel).
+
+
+GUI-MESSAGES:
+
+all gui-objects (bng, hsl, vsl, tgl, rdb, cnv and vu)
+ understand input-messages which change their properties.
+ except cnv has no input, so you have to send messages
+ to its receive-label (edit properties).
+
+"size 15 128" = change width & height of sliders and vu in pixels.
+"size 15" = change square-size of rdb, bng and tgl in pixels.
+"vis_size 800 600" = change width & height of visual rectangle
+ of my_canvas in pixels.
+"range 0.1 10.0" = change slider-boundaries for
+ input- as well as output-values.
+"nonzero 127.0" = change the nonzero-value of toggle.
+"flashtime 50 600" = change flash-interrupt- and
+ flash-hold-time of bng-object.
+"pos 150 170" = change the x-y-position of the top-left
+ corner of a gui-object in pixels;
+ "pos 0 0" is the top-left corner of your window;
+ the positive directions of x- and y-axes are right and down.
+"delta 15 17" = move the gui-object in relation to its
+ current position (in pixels).
+"color 0 22 22" = change background-, front- and
+ label-color of object with one of 30 presets.
+"color 0 22" = change background- and label-color
+ of vu and my_canvas with one of 30 presets.
+"color -16777216 (-1) -1" = change background-, (front-)
+ and label-color of object with RGB-values.
+ the RGB-value will be calculated:
+ -65536*RED-value (0 .. 255)
+ - 256*GREEN-value (0 .. 255)
+ - BLUE-value (0 .. 255) - 1.
+"number 10" = change number of buttons of radio-button.
+"steady 1" change slider-knob-behaviour on mouse-click.
+"single_change" change radio-button-behaviour
+ to output only the new state.
+"double_change" change radio-button-behaviour
+ to first release the previous button,
+ then output the state of the new button.
+"send fromgui" = change send-name of gui-objects,
+ except vu and cnv.
+"receive togui" = change receive-name of object.
+"label its_me" = change label-text of object.
+"label_pos 20 8" = change offset-coordinates of label-text.
+"label_font 0 10" = change font and fontsize of label-text.
+"init 1" = change initial loadbang-mode of gui-objects
+ except vu and cnv.
+"set 64" = change only the inner state and display
+ of gui-objects, except bng and cnv;
+ no output will result.
+"lin" = change scale-mode of slider to linear.
+"log" = change scale-mode of slider to logarithmical.
+"get_pos" = if my_canvas has a receive-name and a send-name
+ and you send the message "get_pos" to it,
+ you receive the current x- and y-coordinates.
