enum XORRenderPasses

Shared code used by the rotate, select, and scale tools to XOR the object(s) being dragged on/off screen. This function is called before starting to XOR the objects onto screen to reset the count of objects which have been rendered (for interruptible blob redraw) and other pertinent information. This should be called once before starting an outline drag, and under normal circumstances need never be called again, as it is called internally by RenderXOROutlinesOff at appropriate times. Author: Jason_Williams (Xara Group Ltd) <camelotdev@xara.com> Date: 22/2/94 Parameters: FlushTheCache  - This should ALWAYS be TRUE in external calls [INPUTS] Notes: For example client code, see the selector and rotate tools. If you fail to call this before starting outline dragging, the cached drag information used by related calls will be wrong, and it'll break. See also: SelRange::RenderXOROutlinesOn; SelRange::RenderXOROutlinesOff; SelRange::RenderXOROutlinesToCatchUp; OpSelectorMove Enumerator: RENDER_START  RENDER_HIGH  RENDER_MEDIUM  RENDER_LOW  RENDER_END  Definition at line 1626 of file range.cpp. { RENDER_START, // About to start rendering passes from the beginning RENDER_HIGH, // Render all high-priority objects RENDER_MEDIUM, // Render all medium-priority objects RENDER_LOW, // Render all low-priority objects (anything that's left!)

static void DrawXORBoundingRect (  RenderRegion *  pRender, DocRect &  TheRect )  [inline, static]

Shared code which renders the bounding rectangle of the XOR outline objects in the current colours. It is rendered as a path so that the rect. Author: Jason_Williams (Xara Group Ltd) <camelotdev@xara.com> Date: 28/4/95 Parameters: pRender  - a render region to render into [INPUTS] TheRect - the current bounding rectanglew of the XOR outline objects Basically just a veneer for DrawDragBounds See also: OSRenderRegion::DrawDragBounds Definition at line 1985 of file range.cpp. { if (!TheRect.IsValid() || TheRect.IsEmpty() || !DocView::OutlineShowBounds) return; #if !defined(EXCLUDE_FROM_RALPH) pRender->SaveContext(); pRender->SetLineColour(COLOUR_XORSELECT); pRender->DrawDragBounds(&TheRect); pRender->RestoreContext(); #endif }

BOOL SafeAppendString (  StringBase *  pstrAppendum, const StringBase &  strAppendee, BOOL  fAddSep = TRUE )

update the status line with the given text, prefixed with the selection description (if valid to do so) Author: Justin_Flude (Xara Group Ltd) <camelotdev@xara.com> Date: 21/7/95 Parameters: pstrAppendum  pointer to the string to append to [INPUTS] strAppendee the string to append fAddSep if TRUE (the default) will append a space after strAppendee string. pstrAppendum  the appended string [OUTPUTS] Returns: TRUE if it was trivial to append, FALSE if the string to be appended had to be truncated. See also: SelRange::LayerDescription Definition at line 5070 of file range.cpp. { INT32 nTotal = pstrAppendum->Length() + strAppendee.Length() + (fAddSep != 0); INT32 nMax = pstrAppendum->MaxLength(); BOOL fNoTrunc= (nTotal < nMax); if (fNoTrunc) { // We can append without fear of overflow . . . *pstrAppendum += strAppendee; if (fAddSep) *pstrAppendum += TEXT(" "); } else { // We have to truncate the string to append, to avoid overflow . . . INT32 nTruncCount = strAppendee.Length() - (nTotal - nMax); if (nTruncCount > 0) { // We have some room for more text, so append the truncated string. String_256 strTrunc; strAppendee.Left(&strTrunc, nTruncCount); *pstrAppendum += strTrunc; if (fAddSep) *pstrAppendum += TEXT(" "); } } // Return FALSE if we had to truncate. return fNoTrunc; }
