Thanks Tomaž, yep I missed the GDK_CROSS on the gtk3 reference page https://developer.gnome.org/gdk3/stable/gdk3-Cursors.html
I am implementing *PointerStyle::FatCross* to be used to diplay a 'fat cross' mouse cursor when hovering the spreadsheet grid. Up to this point, I am only concerned with the GTK3 backend. So far I have done: 1. Expanded the *enum class PointerStyle *to include *FatCross = 96, *in file /libreoffice/include/vcl/ptrstyle.hxx; 2. Changed line 53 of 'fudraw.cxx' from *aNewPointer ( PointerStyle::Arrow ),* to *aNewPointer ( PointerStyle::FatCross ), * 3. Added line *MAP_BUILTIN( PointerStyle::FatCross, GDK_CROSS );* to *GdkCursor *GtkSalDisplay::getCursor( PointerStyle ePointerStyle )* on files *gtkdata.cxx* and *gtk3gtkdata.cxx. *This should do the mapping of *FatCross* from vcl to gtk3. This changes will compile successfully. However, when I start LO-Calc and hover over the cell grid area, the program crashes and displays an 'unexpected error'. My guess is that the *FatCross = 96, *member of *enum class PointerStyle* is not defined correctly. Any idea on what is needed to define *FatCross*? How can I make the *FatCross* work in GTK3? ps: As I said in the email I set earlier: Basically the idea is to change the 'arrow' mouse icon into a 'fat cross' when hovering over calc spreadsheet cell grid. Preliminar investigation reveals that this behaviour can be well approximated if line 53 of file fudraw.cxx is changed from " aNewPointer ( PointerStyle::Arrow )," change into " aNewPointer ( PointerStyle::Cross )," However, the resulting cross looks a litle bit too thin and cannot be used because it is the same mouse cursor used to drag equations around. This is why I created a new PointerStyle::FatCross, so it is different from PointerStyle::Cross, which is currently used to drag equations. 2017-02-06 9:42 GMT+00:00 Tomaž Vajngerl <[email protected]>: > Hi, > > On Fri, Feb 3, 2017 at 10:12 AM, Nuno Ferreira <[email protected]> wrote: > > Another issue is the fact that GTK3+ does not seem to offer the fat cross > > anymore, only the crosshair.... > > https://developer.gnome.org/gdk3/stable/gdk3-Cursors.html.
