thanx!
as i understand it the mouse down event also fires as long as the key is pressed? i guess that would be trouble since i want to delete the item that triggers the deletion?
i do not understand why it should be better to bind inside the mouse click handler?

Hello everyone, I have a wxScrolledWindow populated with wxStaticBitmaps and the selected bitmap is painted with a blue edge. The user can select a bitmap by clicking on it and I want to achieve that pressing the delete key deletes the bitmap. Now, in the bitmaps ctor i use Bind(wxEVT_CHAR, &Scrolle...

YES!!! worked, that was easy, should have thought of it myself.
thank you!

hi everyone, i have a wxGrid cell with a wxGridCellNumberEditor and have a special case where i do not only have an int in that cell of the grid, but i want to show i.e. "45±" instead of just "45". now, it is no problem to remove the "±" before the editor is shown with wxEVT_GRID_EDITOR_SHOWN event,...

I would like to block the main app until either a connection is established or not. I just want this to be as fast as possible. It seems unnecessary to try to establish a wxSocket connection for a couple of seconds if one could somehow quickly check if there is a device at a certain ip adress at all...

good idea! this worked and I found out that the device sometimes needs longer to connect the socket. i used to have WaitOnConnect(2) and that sometimes was too little time. what bugs me is that it might need up to 7 seconds per socket and i have 2 sockets per device and potentially 2 devices. can i ...

Hi,
Did you look at the sample?

Thank you.

yes, it all simply works in the sample, probably because it also has control over the server. That is not the case with me, so i guess my problem has to do with some non wxWidgets socket implementation in the device.

i am happy that it could help someone! i have updated it myself since then and am still using it. i hope something like this will be part of wxwidgets someday.

hi everyone, so this basically works, it just sometimes needs a second run through to be successful. can I improve it? wxIPV4address addrSett; addrSett.Hostname(wxString::Format(wxT("192.168.5.%i"), getLastIpNum())); addrSett.Service(wxString::Format(wxT("%i"), portNr)); bool makeConn = sock->Connec...

I everyone! I want to have some kind of traffic light showing the state of a device connected to my app with either red or green light. I thought about some thing like a mouseOver wxBitmap, only that I control the state and not the mouse. Or just rebuild the whole window and use the other bitmap whe...

I have two functions with different signatures void func1(wxPoint pnt) { OutputDebugString(wxT("wxPoint\n")); } void func1(wxRealPoint pnt) { OutputDebugString(wxT("wxRealPoint\n")); } wxPoint pInt(1, 1); wxRealPoint pDbl(2.0, 2.0); bool choice = true; func1(choice ? pDbl : pInt); No matter what "ch...

thank you all, then I will use 0 as a minimum and check in every new release if this is fixed.

Weird thing with wxSpinCtrlDouble, a minimum of i.e. 5 makes it impossible to manually enter any value starting with 1/2/3/4. wxSpinCtrlDouble *dblTest = new wxSpinCtrlDouble(this, wxID_ANY, wxEmptyString, wxDefaultPosition, wxDefaultSize, wxSP_ARROW_KEYS, 5, 50); It works fine with wxSpinCtrl. Can ...

After a look into the sources, it seems that at least under Windows there's dedicated platform specific code that creates a region from a polygon without rendering it into a bitmap. So it's possible that at least under Windows a wxRegion can be both small and fast. I didn't make any performance tes...

Sounds good, thanx! I would say there will be max 4000 lines. You think wxRegion is much slower than wxRect? To use both like you suggested, I would have to fill and loop at least two vectors. I would tend to only use wxRegion, what do you think? A nice pre test would be if the mouse is between the ...
