14 // The TGButtonGroup widget organizes TGButton widgets in a group. //
15 // //
16 // A button group widget makes it easier to deal with groups of buttons.//
17 // A button in a button group is associated with a unique identifier. //
18 // The button group emits a Clicked() signal with this identifier when //
19 // the button is clicked. Thus, a button group is an ideal solution //
20 // when you have several similar buttons and want to connect all their //
21 // Clicked() signals, for example, to one slot. //
22 // //
23 // An exclusive button group switches off all toggle buttons except //
24 // the one that was clicked. A button group is by default non-exclusive.//
25 // All radio buttons that are inserted, will be mutually exclusive even //
26 // if the button group is non-exclusive. //
27 // //
28 // //
29 // There are two ways of using a button group: //
30 // //
31 // The button group is a parent widget of a number of buttons, //
32 // i.e. the button group is the parent argument in the button //
33 // constructor. The buttons are assigned identifiers 1, 2, 3 etc. //
34 /// in the order they are created or you can specify button id in //
35 // the button constructor. A TGButtonGroup can display a frame and //
36 // a title because it inherits from TGGroupFrame. //
37 // //
38 // Example: //
39 // //
40 // // vertical frame without border and title //
41 // TGVButtonGroup *bg = new TGVButtonGroup(main_frame); //
42 // //
43 // // create text button with id=1 //
44 // TGTextButton *button1 = new TGTextButton(bg,"some text"); //
45 // //
46 // // create another text button with id=2 //
47 // TGTextButton *button2 = new TGTextButton(bg,"another text"); //
48 // //
49 // // map all buttons //
50 // bg->Show(); //
51 // //
52 // NOTE: there is no need to call AddFrame() since the buttons are //
53 // automatically added with a default layout hint to their parent, //
54 // i.e. the buttongroup. To override the default layout hints use the //
55 // SetLayoutHints() method. //
56 // //
57 // ButtonGroup Signals: //
58 // //
59 // Pressed(Int_t id) --> is emitted when a button in the group is //
60 // pressed down. The id argument is the //
61 // button's identifier. //
62 // Released(Int_t id) --> is emitted when a button in the group is //
63 // released. The id argument is the button's //
64 // identifier. //
65 // Clicked(Int_t id) --> is emitted when a button in the group is //
66 // clicked. The id argument is the button's //
67 // identifier. //
68 // //
69 // //
70 // The TGHButtonGroup widget organizes TGButton widgets in a group //
71 // with one horizontal row. TGHButtonGroup is a convenience class that //
72 // offers a thin layer on top of TGButtonGroup. It inherits from //
73 // TGButtonGroup. //
74 // //
75 // The TGVButtonGroup widget organizes TGButton widgets in a group //
76 // with one vertical column. TGVButtonGroup is a convenience class that //
77 // offers a thin layer on top of TGButtonGroup. It inherits from //
78 // TGButtonGroup. //
