I am building a custom win32 control/widget and would like to change the cursor to a horizontal ‘splitter’ symbol when hovering over a particular vertical line in the control. IE: I want to drag this vertical line (splitter bar) left and right (WEST and EAST).
Of the the system cursors (OCR_*), the only cursor that makes sense is the OCR_SIZEWE. Unfortunately, that is the big, awkward cursor the system uses when resizing a window. Instead, I am looking for the cursor that is about 20 pixels tall and around 3 or 4 pixel wide with two small arrows pointing left and right.
I can easily draw this and include it as a resource in my application but the cursor itself is so prevalent that I wanted to be sure it wasn’t missing something.
For example: when you use the COM drag and drop mechanism (CLSID_DragDropHelper, IDropTarget, etc) you implicitly have access to the ‘drag’ icon (little box under the pointer). I didn’t see an explicit OCR_* constant for this guy … so likewise, if I can’t find this splitter cursor outright, I am wondering if it is part of a COM object or something else in the win32 lib.
There are all sorts of icons, cursors, and images in use throughout the Windows UI which are not publicly available to 3rd-party software. Of course, you could still load up the module in which they reside and use them, but there’s really no guarantee your program will keep working after a system update / upgrade.
Include your own. The last thing you want is adding an extra dependency over a tiny little cursor.
