This requires * that a locale hook is provided with the layout handle. * The array is terminated by -1. * * LABX_ReserveSpace (BOOL) - Allocate extra memory to hold * the contents of the lines displayed. This avoids nasty * side-effects when refreshing this object. * Default: FALSE * * LABX_FirstLine (LONG) - Locale string ID of the first * text to print inside the box. Works in conjunction * with LABX_LastLine. (V26) * * LABX_LastLine (LONG) - Locale string ID of the last * text to print inside the box. Works in conjunction * with LABX_FirstLine. (V26) * * LABX_LineTable (LONG *) - Pointer to an array of IDs * to use for building the box contents lines.

(V31) * * LABX_LineID (LONG) - Locale ID of line text to display in the * box, may contain '\n' line break characters, the layout * engine will chop the single line into single consecutive lines * following the '\n' chars. (V31) * * SLIDER_KIND: * * LASL_FullCheck: TRUE will cause the code to rattle * through all possible slider settings, starting * from the minimum value, ending at the maximum value. * While this may be a good idea for a display * function to map slider levels to text strings * of varying length it might be a problem when * it comes to display a range of numbers from * 1 to 40,000: the code will loop through * 40,000 iterations trying to find the longest * string. * * FALSE will cause the code to calculate the * longest level string based only on the * minimum and the maximum value to check. * While this is certainly a good a idea when * it comes to display a range of numbers from * 1 to 40,000 as only two values will be * checked the code may fail to produce * accurate results for sliders using display * functions mapping slider levels to strings. * * Default: TRUE * * * LEVEL_KIND: * * All tags are supported which SLIDER_KIND supports. * The gadget level display however, can only be aligned * to the left border. * * * LISTVIEW_KIND: * * LALV_ExtraLabels (STRPTR *) - Place extra line * labels at the right of the box. Terminate * this array with NULL. * * LALV_Labels (STRPTR *) - The labels to display * inside the box, you can pass this array of * strings in rather than passing an initialized * List of text via GTLV_Labels. Terminate * this array with NULL. * * LALV_CursorKey (BOOL) - Let the user operate this * listview using the cursor keys. * * NOTE: there can be only one single listview * per window to sport this feature. * * Default: FALSE * * LALV_Lines (LONG) - The number of text lines this * listview is to display. * * LALV_Link (LONG) - The Gadget ID of a string gadget * to attach to this listview. * * NOTE: you need to * add the Gadget in question before you add the * listview to refer to it or the layout routine * will get confused. * * Passing the value NIL_LINK will create a listview * which displays the currently selected item, otherwise * you will get a read-only list. * * LALV_FirstLabel (LONG) - Locale string ID of the first * text to use as a list label. Works in conjunction * with LALV_LastLabel. * * LALV_LastLabel (LONG) - Locale string ID of the last * text to use as a list label. Works in conjunction * with LALV_FirstLabel. When building the interface the * code will loop from FirstLabel..LastLabel, look * up the corresponding locale strings and use the * data to make up the label text to appear in the * list. * * LALV_LabelTable (LONG *) - Pointer to an array of IDs * to use for building the listview contents. This requires * that a locale hook is provided with the layout handle. * The array is terminated by -1. * * LALV_MaxGrowX (LONG) - Maximum width of this object * measured in characters. When the first layout pass * is finished and there is still enough space left * to make the listview wider, the width is increased * until it hits the limit specified using this tag. * * NOTE: there can be only one single listview * per window to sport this feature. * * Default: 0 * * LALV_MaxGrowY (LONG) - Maximum height of this object * measured in lines. When the first layout pass is * finished and there is still enough space left to * make the listview higher, the height is increased * until it hits the limit specified using this tag. * * NOTE: there can be only one single listview * per window to sport this feature. * * Default: 0 * * LALV_ResizeX (BOOL) - Makes this listview resizable * in the horizontal direction, attaches a sizing * gadget to the window to open and handles window * resize operations automatically. (V9) * * NOTE: there can be only one single listview * per window to sport this feature. * * Also listen to IDCMP_CLOSEWINDOW events * which may be generated if the layout * engine runs out of memory when rebuilding * the user interface. * * Default: FALSE * * LALV_ResizeY (BOOL) - Makes this listview resizable * in the vertical direction, attaches a sizing * gadget to the window to open and handles window * resize operations automatically. (V9) * * NOTE: there can be only one single listview * per window to sport this feature. * * Also listen to IDCMP_CLOSEWINDOW events * which may be generated if the layout * engine runs out of memory when rebuilding * the user interface. * * Default: FALSE * * LALV_MinChars (WORD) - Minimum width for this * object, measured in characters. Used in * conjunction with LALV_ResizeX. (V9) * * LALV_MinLines (WORD) - Minimum height for this * object, measured in lines. Used in * conjunction with LALV_ResizeY. (V9) * * LALV_LockSize (BOOL) - After doing the initial layout * for this object, do not adapt its size again during * subsequent layouts. This is particularly useful if * you have a LISTVIEW_KIND object in a paged group * and keep adding new entries to the list. You need * to specify an object width using LA_Chars, otherwise * the layout engine may make it not wide enough to * display any entries. (V8) * * LALV_FlushLabelLeft (BOOL) - For a gadget label placed * above the listview align the text to the left edge * of the view. (V9) * * LALV_TextAttr (struct TextAttr *) - You can specify a * fixed-width font to be used for the list display. * The TextAttr (or TTextAttr) you provide must be ready * to go so the layout code can open the font later. * * To get the current system default font, which is * guaranteed to be fixed-width, pass ~0 instead of a * pointer to a TextAttr structure.

When opened, they make the classes they * represent publicly available so subsequent calls to * NewObject(NULL,<Classname>,...) can be made. The * LABO_ClassLibraryName tag will cause gtlayout.library to open * the class library before any calls to NewObject() are made. * * NOTE: Only classes derived from gadgetclass and * gadgetclass itself may be used. * * The LABO_ClassLibraryName tag requires that you * specify the class name with the LABO_ClassName. It is * not enough to just use the LABO_ClassLibraryName tag. * * LABO_ExactWidth (WORD) - This is the exact width of the object to * use.

This effectively overrides whatever you specified using * the LA_Lines tag and keeps gtlayout.library from shrinking and * expanding the object as needed. * * LABO_RelFontHeight (WORD) - This tag affects the height of the * object; when specified, it is derived from the user interface * font height plus the value given with LABO_RelFontHeight. * * LABO_FullWidth (BOOL) - Use this tag if you wish the object to * cover the entire width of the group it resides within. * * LABO_FullHeight (BOOL) - Use this tag if you wish the object to * cover the entire height of the group it resides within. * * LABO_ActivateHook (struct Hook *) - Hook to invoke when the * layout engine decides that this particular object should * be activated. The hook is called with the following * parameters: * * Success = ActivateFunc(struct Hook *Hook,LayoutHandle *Handle, * D0 A0 A2 * * Object *object) * A1 * * The object pointer actually refers to the instance of the * BOOPSI object created. Return FALSE if your object could not * be activated, TRUE if it worked. If you return TRUE, no special * keyboard event will be generated. (V13) * * NOTE: All tags passed to LT_New() for BOOPSI_KIND objects are * passed through to NewObjectA() later. The library makes * a copy of the tag item list, so all data valid in the * scope when LT_New() is called must also be valid later * when LT_Build() is invoked. * * The gadget label is *NOT* passed through to the object, * it effectively receives the label a plain gadtools object * would receive, similar to what happens to FRAME_KIND * objects and the like. * * RESULT * none * * BUGS * Up to v25 the SCROLLER_KIND object did not support GA_Immediate * or GA_RelVerify. The space for the variables was there, but the * code was missing. * * POPUP_KIND objects don't work well in simple refresh windows, * as refresh events can get lost.
