Tabs don't display in NB's "overwrite" mode as they used to. This also afects how jVi displays over a tab char. The following shows what NB's ExtCaret.paint() is seeing. The first two lines are over a regular character and the next lines are after moving the caret down one line onto a tab character. It is interesting how the clip region changes after moving to the next line. ==ModelToView== ==Graphics.getClipBounds== Rect[x=0,y=153,width=8,height=17] Rect[x=0,y=153,width=8,height=17] Rect[x=0,y=153,width=8,height=17] Rect[x=0,y=153,width=8,height=17] KeyAction: ViDownKey: e001(1) 0 virt Rect[x=0,y=170,width=1,height=17] Rect[x=0,y=153,width=447,height=51] Rect[x=0,y=170,width=1,height=17] Rect[x=0,y=153,width=447,height=17] Rect[x=0,y=170,width=1,height=17] Rect[x=0,y=170,width=2,height=17] Rect[x=0,y=170,width=1,height=17] Rect[x=0,y=170,width=2,height=17] Somewhat OffTopic, though related. In .../view/NewlineView.java there is the following code which handle a similar issue with newline. I'm confused about a part of it. For axis==View.X_AXIS when not showNonPrint defaultLineHeight is returned. At first glance it seems incorrect to be returning any height for X_AXIS. Before the change this was an "advance", which I still don't entirely understand from the javadoc, but it does seem to be an "X" thing. So the use of line height might be a bug. @Override public float getPreferredSpan(int axis) { // Although the width could be e.g. 1 return a default width of a character // since if caret is blinking over the newline character and the caret // is in overwrite mode then this will make the caret fully visible. DocumentView documentView = getDocumentView(); if (axis == View.X_AXIS) { return (documentView != null) ? (documentView.isShowNonprintingCharacters() ? documentView.getDefaultLineHeight() : documentView.getDefaultCharWidth()) : 1; // Only return one if not connected to view hierarchy } else { return (documentView != null) ? documentView.getDefaultLineHeight() : 1; } }
This report is before the big changes in the views. I am closing as works for me. If still a problem in 7.3 or later please reopen.
