Summary: Control: After a MouseDown event a MouseMove with
different coords is fired
Product: Mono: Class Libraries
Version: SVN
Platform: i686
OS/Version: openSUSE 10.3
Status: NEW
Severity: Normal
Priority: P5 - None
Component: Windows.Forms
AssignedTo: mono-bugs@lists.ximian.com
ReportedBy: [EMAIL PROTECTED]
QAContact: mono-bugs@lists.ximian.com
Found By: ---
I found this problem with controls using InternalBorderStyle=BorderStyle3D
(probably any control using non-default border has the same problem). Example
of such controls: ListBox, TreeView, ListView.
Clicking with the left mouse button generates first a MouseDown, and
immediately a MouseMove event with _different_ coords than MouseDown ones. This
makes controls using SystemInformation.DragSize be confused and firing random
dnd operations.
Clicking with left button should generate both MouseDown and MouseMove but with
_same_ coords.
*Observe that a slighly different result appears when right-clicking instead of
left-clicking.
Reproduce:
1. Compile the attached sample.
2. Left-click on the form, and observe the console output - MouseDown has
different x,y coords than MouseMove, while .net are same.
