Hi all, I'm trying to enhance the patch for fdo#40465 as the patch results in behaviour that in some cases is a regression. When zooming I want to know if the cursor is visible. The function SwCrsrShell::CrsrIsVisible() some times returns sal_False when the cursor absolutely is visible in the view.
I collected some traces of the cursor position and of the visible area (SwCrsrShell::aVisArea) and to my amazement the area differs between two (visually) identical views. I opened a writer document with 22 pages, scrolled to page 16, with cursor at page 16. SwCrsrShell::CrsrIsVisible() returns sal_True, zoom % is 60, SwCrsrShell::aVisArea.Top(), Bottom() give 170460 and 188635. I then move the cursor one line down and back (no scrolling), zoom to 55% and back to 60%. The visible area looks identical, the cursor is back in the same location. Now SwCrsrShell::CrsrIsVisible() returns sal_True, zoom % is 60, SwCrsrShell::aVisArea.Top(), Bottom() give 115860 and 134035. The cursor rectangle position has not changed and now is not in SwCrsrShell::aVisArea (cursor top/bottom is 121272/122191). What is the explanation for this behaviour? If this is 'normal', how can I (jn the code) find out if the cursor is visible? If required, I can upload the document as well as the code for the trace into bug fdo#40465. Winfried
