This way double conversions +and rounding errors are avoided and the ruler displays the margins +at their actual position in the document. Because of this, the application can, +for example in tables, do its own roundings and the positions on the ruler will +still match those in the document. However, for the ruler to know how the +document is displayed on the screen, some additional values have to be configured + +SetWinPos() sets the offset of the ruler's edit window. In doing so, +the width of the window can also be configured. If there is a 0 among the +values passed to the function, the position/width is automatically set to +the width of the ruler. + +SetPagePos() sets the offset of the page relative to the edit window and the +width of the page. If there is a 0 among the values passed to the function, +the position/width is automatically set as if the page filled the whole edit window. + +SetBorderPos() sets the offset of the border. The position is relative to +the upper/left margin of the window. This is needed when there are a horizontal +and a vertical ruler visible at the same time. Example: + aHRuler.SetBorderPos( aVRuler.GetSizePixel().Width()-1 ); + +SetNullOffset() sets the origin relative to the page. + +All the other values (margins, indentation, tabs, ...) refer to the origin, +which is set with SetNullOffset(). + +The values are computed as described below: + +- WinPos (if both windows have the same parent) + + Point aHRulerPos = aHRuler.GetPosPixel(); + Point aEditWinPos = aEditWin.GetPosPixel(); + aHRuler.SetWinPos( aEditWinPos().X() - aHRulerPos.X() ); + +- PagePos + + Point aPagePos = aEditWin.LogicToPixel( aEditWin.GetPagePos() ); + aHRuler.SetPagePos( aPagePos().X() ); + +- All other values + + Add the logical values, recompute as position and subtract the + previously saved pixel positions (of PagePos and Null Offset). + +-------------------------------------------------------------------------- + +SetUnit() and SetZoom() configure which unit is used to display +the values on the ruler. The following units are accepted: + + FieldUnit::MM + FieldUnit::CM (Default) + FieldUnit::M + FieldUnit::KM + FieldUnit::INCH + FieldUnit::FOOT + FieldUnit::MILE + FieldUnit::POINT + FieldUnit::PICA + +-------------------------------------------------------------------------- + +SetMargin1() sets the upper/left margin and SetMargin2() sets the +bottom/right margin. If these methods are called without arguments, +no margins are displayed. Otherwise, the following arguments can be passed: + + long nPos - offset in pixels relative to the origin + sal_uInt16 nStyle - bit style: + RULER_MARGIN_SIZEABLE + margin size can be changed + + The following bits can be set in addition + to these styles: + RULER_STYLE_INVISIBLE + + +SetBorders() sets an array of margins. To do this, an array of type RulerBorder +has to be passed. In the array, the following values have to be initialized: + + long nPos - offset in pixels relative to the origin + long nWidth - column spacing in pixels (can also be 0, for example, + for table columns) + sal_uInt16 nStyle - bit style: + RulerBorderStyle::Sizeable + Column spacing can be changed. This flag should + only be set if the size of the spacing is changed, + not that of a cell. + RulerBorderStyle::Moveable + Column spacing/border can be moved. Whenever + table borders are to be moved, this flag should + be set instead of SIZEABLE (SIZEABLE indicates + that the size of a spacing, not that of a single + cell can be changed). + RulerBorderStyle::Variable + Not all of the column spacings are equal + RulerBorderStyle::Table + Table border. Whenever this style is set, the column + width must be 0. + RulerBorderStyle::Snap + Auxiliary line. Whenever this style is set, the + column width must be 0. + RulerBorderStyle::Margin + Margin. Whenever this style is set, the column + width must be 0. + + The following bits can be set in addition + to these styles: + RULER_STYLE_INVISIBLE + +SetIndents() sets an array of indents. This method may only be used for horizontal +rulers. A Ruler Indent must be passed as an argument, with the following values +initialized: + + long nPos - offset relative to the origin in pixels + sal_uInt16 nStyle - bit style: + RulerIndentStyle::Top (indent of the first line) + RulerIndentStyle::Bottom (left/right indent) + RulerIndentStyle::Border (Vertical line that shows the border distance) + The following bits can be set in addition + to these styles: + RULER_STYLE_DONTKNOW (for old position or for + ambiguity) + RULER_STYLE_INVISIBLE + +SetTabs() sets an array of tabs. This method may only be used for horizontal rulers. +An array of type RulerTab must be passed as an argument, with the following values +initialized: + + long nPos - offset relative to the origin in pixels + sal_uInt16 nStyle - bit style: + RULER_TAB_DEFAULT (can't be selected) + RULER_TAB_LEFT + RULER_TAB_CENTER + RULER_TAB_RIGHT + RULER_TAB_DECIMAL + The following bits can be set in addition + to these styles: + RULER_STYLE_DONTKNOW (for old position of for + ambiguity) + RULER_STYLE_INVISIBLE + +SetLines() displays position lines in the ruler. An array of type RulerLine must be passed, with +the following values initialized: + + long nPos - offset relative to the origin in pixels + sal_uInt16 nStyle - bit style (has to be 0 currently) + +-------------------------------------------------------------------------- + +If the user should also be able to change the margins tabs, borders, ... +in the ruler, a bit more effort is necessary. In this case, the StartDrag(), +Drag() and EndDrag() methods have to be overridden. For the StartDrag() method +it is possible to prevent dragging by returning FALSE. In the drag handler, +the drag position must be queried and the values must be moved to the new +position. This is done by calling the particular Set methods. While in the +drag handler, the values are just cached and only afterward the ruler is redrawn. +All the handlers can also be set as links with the particular Set..Hdl() methods. + + - StartDrag() + Is called when dragging is started. If FALSE is returned, the dragging. + won't be executed. If TRUE is returned, the dragging will be permitted. + If the handler isn't overridden, FALSE will be returned. + + - EndDrag() + Is called at the end of dragging. + + - Drag() + Is called when dragging takes place. + + - Click() + This handler is called when no element has been clicked on. + The position can be queried with GetClickPos(). This way it is possible + to, for example, ser tabs in the ruler. After calling the click handler, + the drag, if any, is immediately triggered. This makes it possible to + set a new tab in the click handler and then immediately move it. + + - DoubleClick() + This handler is called when a double-click has been performed outside + the special panel. The methods GetClickType(), GetClickAryPos() and + GetClickPos() can be used to query what has been clicked on. + This way you can, for example, show the tab dialog when a double-click + is performed on a tab. + +In the drag handler it is possible to query what has been dragged and where +it has been dragged. There are the following query methods: + + - GetDragType() + Returns what has been dragged. + RulerType::Margin1 + RulerType::Margin2 + RulerType::Border + RulerType::Indent + RulerType::Tab + + - GetDragPos() + Returns the pixel position to which the user has moved the mouse + relative to the set zero-offset. + + - GetDragAryPos() + Returns the index in the array if a border, an indent or a tab + is being dragged. Attention: During a drag process, the array position + of the item that has been set before the drag is returned. + Therefore, it is for example also possible, to no longer show a tab + if the mouse is dragged out of the ruler in bottom/right direction. + + - GetDragSize() + If Borders are dragged, this can be used to query whether the size + resp. which side or the position should be changed. + RulerDragSize::Move or 0 - Move + RulerDragSize::N1 - left/upper border + RulerDragSize::N2 - right/bottom border + + - IsDragDelete() + This method can be used to query whether the mouse has been + moved out of the window at the bottom/right while dragging. + By this, it can for example be determined whether the user + wants to delete a tab. + + - IsDragCanceled() + Using this Handler, it can be queried in the EndDrag handler + whether the action was canceled by the user releasing the + mouse at the top/left of the window or by pressing ESC. + In this case, the values are not applied. If during the + dragging, the mouse is dragged out of the window at the + top/left, the old values are displayed automatically without + the Drag handler being called. + But if the user has moved the value to the old position, the + method returns 'false' nevertheless. + If this should be avoided, the application must remember the + old value in the StartDrag handler and compare the value in the + EndDrag handler. + + - GetDragModifier() + Returns the modifier keys that were pressed when the Drag process + was started. See MouseEvent. + + - GetClickPos() + Returns the pixel position at which the user has pressed the mouse + with respect to the configured null-offset. + + - GetClickType() + Returns what is applied by double click: + RulerType::DontKnow (no element in the ruler area) + RulerType::Outside (outside of the ruler area) + RulerType::Margin1 (only Margin1 border) + RulerType::Margin2 (only Margin2 border) + RulerType::Border (Border: GetClickAryPos()) + RulerType::Indent (indent: GetClickAryPos()) + RulerType::Tab (Tab: GetClickAryPos()) + + - GetClickAryPos() + Returns the index in the array if a Border, an Indent or a Tab + is applied via DoubleClick. + + - GetType() + This method can be used to carry out a HitTest, + in order to possibly also apply sth to an Item using the right + mouse button by catching the MouseButtonDown handler. As + parameters, the window position and possibly a pointer to a + sal_uInt16 are passed, in order to determine the array position + of a Tab, an Indent, or a Border. The following values are + returned as type: + RulerType::DontKnow (no element in the ruler area) + RulerType::Outside (outside of the ruler area) + RulerType::Margin1 (only Margin1 border) + RulerType::Margin2 (only Margin2 border) + RulerType::Border (Border: GetClickAryPos()) + RulerType::Indent (indent: GetClickAryPos()) + RulerType::Tab (Tab: GetClickAryPos()) + +If the drag process should be canceled, this can be done using CancelDrag(). +There are the following methods for controlling the Drag: + + - IsDrag() + Returns 'true' if the ruler is in a drag process. + + - CancelDrag() + Cancels the drag process, if one is being carried out. During this, + the old values are restored and the Drag and the EndDrag handlers + are called. + +In order to trigger a Drag from the document, there are the following +methods: + + - StartDocDrag() + This method is passed the MouseEvent of the document window + and what should be dragged. If RulerType::DontKnow is passed + as DragType, the ruler decides what should be dragged. In case + of the other types, the Drag is only started if a respective + element was found at the given position. + This is for example necessary if indents and columns are located + at the same X position. + The return value indicates whether the Drag has been triggered. + If a Drag is triggered, the ruler takes over the normal drag + control and behaves as if the ruler had been clicked directly. + Thus, the ruler captures the mouse and also takes over control + of the Cancel (via keyboard, or if the mouse is moved outside + of the ruler above it or left of it). All handlers are called, + too (including the StartDrag handler). If a MouseEvent with + ClickCount 2 is passed, the DoubleClick handler is also called, + respectively. + +-------------------------------------------------------------------------- + +For the extra field, the content can be determined and there are handlers +that can be used to handle specific actions. + + - ExtraDown() + This handler is called when the mouse is pressed in the extra field. + + - SetExtraType() + With this method, it can be defined what should be displayed in + the extra field. + - ExtraType what should be displayed in the extra field + RulerExtra::DontKnow (nothing) + RulerExtra::NullOffset (coordinate axes) + RulerExtra::Tab (Tab) + - sal_uInt16 nStyle bit field as style: + RULER_STYLE_HIGHLIGHT (selected) + RULER_TAB_... (a Tab style) + + - GetExtraClick() + Returns the number of mouse clicks. By this, it is for example + also possible to trigger an action by a DoubleClick in the + extra field. + + - GetExtraModifier() + Returns the modifier keys that were pressed when the extra field + was clicked. See MouseEvent. + +-------------------------------------------------------------------------- + +Further helper functions: + +- static Ruler::DrawTab() + With this method, a Tab can be output on an OutputDevice. + By this, it is also possible to show the Tabs in dialogs like + they are drawn in the ruler. + + This method outputs the Tab centred at the given position. The size + of the tabs can be defined by the defines RULER_TAB_WIDTH and + RULER_TAB_HEIGHT. + +-------------------------------------------------------------------------- + +Tips for the use of the ruler: + +- For the ruler, neither in the Drag mode nor elsewhere, the setting + of the values must be bracketed in SetUpdateMode(). The ruler itself + takes care that, if multiple values are set, they are automatically + grouped together and output flicker-free. + +- Initially, the sizes, positions and values should be set first for the + ruler, before it is displayed. This is important because otherwise + many values are calculated unnecessarily. + +- When the document window, in which the ruler resides, becomes active + resp. unactive, the methods Activate() and Deactivate() should be + called by the ruler. That is so because the display is switched according + to the settings and the system. + +- For example, while dragging Tabs and Indents, the old positions should + also be shown if possible. For that, while setting the Tabs and Indents, + the old positions should be inserted first into the array in addition + and be linked with the style RULER_STYLE_DONTKNOW. After that, the + remaining values should be set in the array. + +- In case of multiple selected paragraphs and table cells, the Tabs and + Indents should be displayed in grey in front of the first cell resp. + the first paragraph. This can also be achieved by the style + RULER_STYLE_DONTKNOW. + +- The measuring arrow should always be shown when the Alt key (WW-Like) + is pressed during the drag. Maybe, this setting should be configurable + always and possibly the measuring arrows always be shown while + dragging. For all settings, the values should always be rounded to the + multiple of one value because the screen resolution is very imprecise. + +- DoubleClicks should be handled in the following way (GetClickType()): + - RulerType::DontKnow + RulerType::Margin1 + RulerType::Margin2 + If the conditions GetClickPos() <= GetMargin1() or + GetClickPos() >= GetMargin2() are met or the type is equal to + RulerType::Margin1 or RulerType::Margin2, a side dialog should + be displayed in which the focus is at the respective border. + - RulerType::Border + A column or table dialog should be shown in which the focus + is at the respective column that can be queried using + GetClickAryPos(). + - RulerType::Indent + The dialog, in which the indents can be configured, should be + shown. In this, the focus should be on the indent which can + be queried using GetClickAryPos(). + - RulerType::Tab + A TabDialog should be displayed in which the Tab, that can be + queried using GetClickAryPos(), should be selected. + +*************************************************************************/ + + +constexpr WinBits WB_EXTRAFIELD = 0x00004000;
