hi, i have the strange behaviour that my cursor disappears in a wxEVT_LEFT_UP event. the position seems to be ok, i tested with: void onLeftUp(wxMouseEvent &evt) { POINT pos; GetCursorPos(&pos); wxPoint pos2 = wxGetMousePosition(); bool test2 = GetCursor().IsOk(); evt.Skip(); } pos and pos2 ...

that is hidden well
thanx!

it seems like a simple question, but i failed to find the solution:
in a wxScrolled<wxPanel>, how can i get the height of the horizontal scrollbar, or the width of the vertical one?
thanx!

perfect, thanx again!
just for anyone with the same problem, this is the result of doublemax´s solution:

hi everyone, for a multi page document, i am creating a scrolled window showing previews of all pages like it is common with pdf viewers. so i have a big bitmap like this: fullsize.gif and when i create my preview image using stretchBlit, it looks like this: previewWrong.gif it is kind of similar, b...

hi everyone, i am planning to have some kind of multiple page preview scrolled window like it is common in pdf readers. i would like to reorder pages in that panel using drag and drop and insert new pages through a right-click menu. is there some wx component other than wxScrolledWindow to do most o...

treeSpaceScrennshot.jpg here is the minimal project working in msw, i ignored encapsulation to keep it simpler: #ifndef __app_h__ #define __app_h__ #include <wx/treectrl.h> #include <wx/dragimag.h> #include <wx/dcbuffer.h> // little red arrow to the left/right to mark the drag position class Positi...

got it to work. just in case anyone has the same problem: a) do not use wxTreeCtrl´s own EVT_TREE_BEGIN_DRAG events, so the item under the dragging mouse is not highlighted. instead, use wxDragImage (see documentation) although i am not sure why it should be of any more use than a simple wxStaticBit...

hi everyone, i want to have drag and drop inside a wxTreeCtrl, but the way it is now, only nodes can be highlighted as the drag target, not the space between. so, can i somehow: a) disable highlighting a node when some other node is dragged on top of it b) show a line between nodes so the user can s...

hi,
i have a wxTreeCtrl that by default processes a doubleclick and WXK_RETURN KeyEvent as wxEVT_TREE_ITEM_ACTIVATED. can i somehow get rid of the WXK_RETURN? ToggleWindowStyle(wxWANTS_CHARS) does not work.
thanx!

ok, since nobody has an idea, i just did it the standard way. works fine, just feels a bit unelegant. this is something i miss in wxWidgets, like a map on an image in html: <img src="image.jpg" width="222" height="152" usemap="#Map"> <map name="Map">...

hi everyone, i have a tool in my app that is basically a line that can be rotated by 90 degrees: rotate1.gif the white circle is the rotation center. it is a wxPanel with a wxBitmap drawn in an OnPaint event. on the circle arrows there is a wxWindow with a wxTRANSPARENT_WINDOW style. one can grab th...

i am not sure if the following has something to do with this thread. i get this access violation error and have a hard time finding the cause: Ausnahme (erste Chance) bei 0x009295C0 (wxmsw30ud_core_vc_custom.dll) in myApp.exe: 0xC0000005: Zugriffsverletzung beim Lesen an Position 0xDDDDDDE1 Ausnahme...

thanx pb, now i understand that this could be a very costly function. i found this dirty trick: rename(fileName, fileName) using the SAME filename. http://stackoverflow.com/questions/1048592/how-to-check-if-a-file-has-been-opened-by-another-application-in-c works at least under windows, still in win...

oh yeah, i forgot that in my last post. wxFileName::IsDirWritable also return true. it sais it the docs Write permissions on a directory mean that you can create new files in the directory. but i would like to test if i can rename the directory, not if i can create new files in it. in the windows ex...
