# File 'lib/ffi-tk/widget/spinbox.rb', line 6 def self.tk_command 'spinbox' end |
Instance Method Details
#bbox(index) ⇒ Object
Returns a list of four numbers describing the bounding box of the character given by index. The first two elements of the list give the x and y coordinates of the upper-left corner of the screen area covered by the character (in pixels relative to the widget) and the last two elements give the width and height of the character, in pixels. The bounding box may refer to a region outside the visible area of the window.
18 19 20 |
# File 'lib/ffi-tk/widget/spinbox.rb', line 18 def bbox(index) execute(:bbox, index).to_a(&:to_i) end |
#delete(first, last = None) ⇒ Object
Delete one or more elements of the spinbox. First is the index of the first character to delete, and last is the index of the character just after the last one to delete. If last is not specified it defaults to first+1, i.e. a single character is deleted. This command returns an empty string.
28 29 30 |
# File 'lib/ffi-tk/widget/spinbox.rb', line 28 def delete(first, last = None) execute_only(:delete, first, last) end |
#get ⇒ Object
Returns the spinbox’s string.
33 34 35 |
# File 'lib/ffi-tk/widget/spinbox.rb', line 33 def get execute(:get) end |
#icursor(index) ⇒ Object
Arrange for the insertion cursor to be displayed just before the character given by index.
39 40 41 |
# File 'lib/ffi-tk/widget/spinbox.rb', line 39 def icursor(index) execute_only(:icursor, index) end |
#identify(x, y) ⇒ Object
Returns the name of the window element corresponding to coordinates x and y in the spinbox. Return value is one of: none, buttondown, buttonup, entry.
46 47 48 |
# File 'lib/ffi-tk/widget/spinbox.rb', line 46 def identify(x, y) execute(:identify, x, y).to_sym end |
#index(index) ⇒ Object
Returns the numerical index corresponding to index.
51 52 53 |
# File 'lib/ffi-tk/widget/spinbox.rb', line 51 def index(index) execute(:index, index) end |
#insert(index, string) ⇒ Object
Insert the characters of string just before the character indicated by index. Returns an empty string.
57 58 59 |
# File 'lib/ffi-tk/widget/spinbox.rb', line 57 def insert(index, string) execute_only(:insert, index, string) end |
#invoke(element) ⇒ Object
Causes the specified element, either buttondown or buttonup, to be invoked, triggering the action associated with it.
63 64 65 |
# File 'lib/ffi-tk/widget/spinbox.rb', line 63 def invoke(element) execute(:invoke, element) end |
#scan_dragto(x) ⇒ Object
This command computes the difference between its x argument and the x argument to the last scan mark command for the widget. It then adjusts the view left or right by 10 times the difference in x-coordinates. This command is typically associated with mouse motion events in the widget, to produce the effect of dragging the spinbox at high speed through the window.
81 82 83 |
# File 'lib/ffi-tk/widget/spinbox.rb', line 81 def scan_dragto(x) execute_only(:scan, :dragto, x) end |
#scan_mark(x) ⇒ Object
Records x and the current view in the spinbox window; used in conjunction with later scan dragto commands. Typically this command is associated with a mouse button press in the widget.
71 72 73 |
# File 'lib/ffi-tk/widget/spinbox.rb', line 71 def scan_mark(x) execute_only(:scan, :mark, x) end |
#selection_adjust(index) ⇒ Object
Locate the end of the selection nearest to the character given by index, and adjust that end of the selection to be at index (i.e. including but not going beyond index). The other end of the selection is made the anchor point for future select to commands. If the selection is not currently in the spinbox, then a new selection is created to include the characters between index and the most recent selection anchor point, inclusive.
93 94 95 |
# File 'lib/ffi-tk/widget/spinbox.rb', line 93 def selection_adjust(index) execute_only(:selection, :adjust, index) end |
#selection_clear ⇒ Object
Clear the selection if it is currently in this widget. If the selection is not in this widget then the command has no effect.
99 100 101 |
# File 'lib/ffi-tk/widget/spinbox.rb', line 99 def selection_clear execute_only(:selection, :clear) end |
#selection_element(element = None) ⇒ Object
Sets or gets the currently selected element. If a spinbutton element is specified, it will be displayed depressed.
105 106 107 |
# File 'lib/ffi-tk/widget/spinbox.rb', line 105 def selection_element(element = None) execute(:selection, :element, element) end |
#selection_from(index) ⇒ Object
Set the selection anchor point to just before the character given by index. Does not change the selection.
111 112 113 |
# File 'lib/ffi-tk/widget/spinbox.rb', line 111 def selection_from(index) execute_only(:selection, :from, index) end |
#selection_present ⇒ Object
Returns 1 if there is are characters selected in the spinbox, 0 if nothing is selected.
117 118 119 |
# File 'lib/ffi-tk/widget/spinbox.rb', line 117 def selection_present execute(:selection, :present).to_boolean end |
#selection_range(from, to) ⇒ Object
Sets the selection to include the characters starting with the one indexed by start and ending with the one just before end. If end refers to the same character as start or an earlier one, then the spinbox’s selection is cleared.
125 126 127 |
# File 'lib/ffi-tk/widget/spinbox.rb', line 125 def selection_range(from, to) execute(:selection, :range, from, to) end |
#selection_to(index) ⇒ Object
If index is before the anchor point, set the selection to the characters from index up to but not including the anchor point. If index is the same as the anchor point, do nothing. If index is after the anchor point, set the selection to the characters from the anchor point up to but not including index. The anchor point is determined by the most recent select from or select adjust command in this widget. If the selection is not in this widget then a new selection is created using the most recent anchor point specified for the widget. Returns an empty string.
139 140 141 |
# File 'lib/ffi-tk/widget/spinbox.rb', line 139 def selection_to(index) execute(:selection, :to, index) end |
#set(string = None) ⇒ Object
If string is specified, the spinbox will try and set it to this value, otherwise it just returns the spinbox’s string. If validation is on, it will occur when setting the string.
146 147 148 149 150 151 152 |
# File 'lib/ffi-tk/widget/spinbox.rb', line 146 def set(string = None) if None == string execute(:set) else execute_only(:set, string) end end |
#validate ⇒ Object
This command is used to force an evaluation of the validateCommand independent of the conditions specified by the validate option. This is done by temporarily setting the validate option to all. It returns 0 or 1.
158 159 160 |
# File 'lib/ffi-tk/widget/spinbox.rb', line 158 def validate execute(:validate).to_boolean end |
#xview(index = None) ⇒ Object
Returns a list containing two elements. Each element is a real fraction between 0 and 1; together they describe the horizontal span that is visible in the window. For example, if the first element is .2 and the second element is .6, 20% of the spinbox’s text is off-screen to the left, the middle 40% is visible in the window, and 40% of the text is off-screen to the right. These are the same values passed to scrollbars via the -xscrollcommand option.
Adjusts the view in the window so that the character given by index is displayed at the left edge of the window.
173 174 175 176 177 178 179 |
# File 'lib/ffi-tk/widget/spinbox.rb', line 173 def xview(index = None) if None == index execute(:xview) else execute_only(:xview, index) end end |
#xview_moveto(fraction) ⇒ Object
Adjusts the view in the window so that the character fraction of the way through the text appears at the left edge of the window. Fraction must be a fraction between 0 and 1.
184 185 186 |
# File 'lib/ffi-tk/widget/spinbox.rb', line 184 def xview_moveto(fraction) execute(:xview, :moveto, fraction) end |
#xview_scroll(number, what) ⇒ Object
This command shifts the view in the window left or right according to number and what. Number must be an integer. What must be either units or pages or an abbreviation of one of these. If what is units, the view adjusts left or right by number average-width characters on the display; if it is pages then the view adjusts by number screenfuls. If number is negative then characters farther to the left become visible; if it is positive then characters farther to the right become visible.
