I'm currently trying to use the printing facility that wx provides, but i'm facing a problem: when i want to change the document size. i use this: MyPrintout::MyPrintout() :wxPrintout( "Test" ) { wxPrintout::SetPageSizeMM(10,10); } but the document size doesnt get affected at all. any idea...

we dont allow printing, we just need a preview for our cutting hardware. thats diffrent to a printer - we dont have endpoints here

how do you mean a layer? a layer supporting to convert our data to what? which class?

instead of drawing everything on our own, we simply would want to pass the data (line from, line to) to some object that produces the output. Do you have an example of that output? not really. we only grab data from vectorized files (AI, EPS, PS ...) and store it in our own structures struct sPoint...

hi there, i'm working on a project to communicate with cutting plotters for cutting out vectorized data. we now would want to integrate a printing / cutting preview. instead of drawing everything on our own, we simply would want to pass the data (line from, line to) to some object that produces the ...

can you show me some code (Thread creation, thread code itself, flags of the socket)

hi, we try to determine the current version of the used program with the following code fragments: wxHTTP get; get.SetHeader( "Content-type", "text/html; charset=utf-8" ); get.SetTimeout(60); while( !get.Connect("www.test.com") ) Sleep(5); wxInputStream *httpStream = ge...

it is not allowed and supported to distribute programs that are compiled in debug mode. this "application configuration..." stuff is from winSXS. winSXS handles different library versions and does not support debug libraries. so when you want to distribute your software compile every singl...

thanks i fixed it.
had to change the creation of the DC to be dynamic and not static and then to delete the dc bevore adding the mask.

thank you both for your ideas, works great, looks good

Maybe I don't understand what you want to do, but maybe you could get away with using the last argument of void DrawBitmap(const wxBitmap& bitmap, wxCoord x, wxCoord y, bool transparent) So I'm guessing you should be able to do something like this: wxMemoryDC pdc( *m_pkBmpPreview ); //clear bac...

it would be ok for me if i need to do raw bitmap access, if i can set the background to transparent.
do you have any references for me how to do that?

hi there, i'm currently rendering graphics with cairo into a dc of a panel. with cairo I can set rgba values for everything. because I have multiple graphics I need to render, I create a wxMemoryDC connected with a bitmap: wxMemoryDC pdc( *m_pkBmpPreview ); and draw into that MemoryDC after renderin...

when you close the wxFrame thats set to SetTopWindow, every instance will close too. One time it happened to me that i forgot to set this window as parent in c'tor of another frame. that was the reason why it still ran on.

you can use cairo for drawings. cairo also supports more logical modes and that stuff.
you can easily get a dc from e.g. a wxPanel and pass it over to cairo

its relatively easy. the way how to zoom by using SetUserScale is known (link above), also moving inside a zoomed image (drag and drop event, SetDeviceOrigin). To calculate backwars what position a click originally had i came to this conclusion: eventPoint = event.GetPosition(); eventPoint.x *= m_fZ...

got it
