Re: compiling wxpdfdocument on linux
The build system of wxPdfDocument uses libtool. If you link against libwxcode_gtk3u_pdfdoc-3.0.la , all should work, since this libtool file contains references to all required dependencies like wxWidgets libraries and fontconfig library. Regards, Ulrich I am trying to install your library on a new...

Re: Try Catch Not Catching - Converting String To Int
I dont want it to throw any error. I just want to assign the return value -1 and then continue execution.
I have passed
"?" <-- actual data
"#143" <-- actual data
Its frustrating that it stops execution when it should be caught and suppressed

Re: C++ Parsing TimeZone From Date String
The api that I invoke returns a date in this similar format "2020-04-17T09:30:00-04:00" and I would like to put that into a unix/epoch form (in my time zone)

Re: C++ Parsing TimeZone From Date String
Hello doublemax, You have helped me so much over the years and I thank you! The api returns the data "2020-04-17T09:30:00-04:00" but i could strip the extra : out of what it returns (I didnt write the api, I only invoke/consume) I will be the first to admit, I have alot to learn when its c...

Re: C++ Parsing TimeZone From Date String
This value is returned from the api "2020-04-17T09:30:00-04:00" which is EST time zone and I need to convert it to CST but I am unsure really how to do this with built in functions of C++ and/or wxwidgets There is some weird timezone / daylight savings time calculations that apparently mak...

Re: Best Graphics Library For Drawing Text/Graphs On Huge Resolution
also that resolution is the equivalent of 16 (4x4) 1920x1080 monitors so I am concerned with refresh performance

Re: Best Graphics Library For Drawing Text/Graphs On Huge Resolution
its basically the stock market. I dont really have a frame rate but will need to 'redraw' or update regions of the screen as they come in. Updates could be as fast as 2x a second. It will just be a passive display.

Best Graphics Library For Drawing Text/Graphs On Huge Resolution
Hello, I am working on designing an application that has a resolution of 7680x4320 (its 4 - 4k monitors put together) in a linux environment. The monitors will display very small 8pt font letters and have historical graph information. What is the best graphics library to use for this? I doubt having...

Re: wxMemoryDC::getPixel returning null
Thank you for the reply. GetPixels is returning false
I am not sure how to get the RGB of a X,Y pixel of a wxNativePixelData. Do you know how I would do this?
wxNativePixelData npd(m_bmpSelectedWord);
npd.GetPixels() // unsure how this works or if it is even right

Hello, I recently updated my system (linux) and now wxMemoryDC::getPixel(x, y, wxColour) is returning null. I basically need to check and see if all the verticle pixels of an image are white. wxColour col; wxMemoryDC dc(m_bmpSelectedImg); for(int j = 0; j < m_bmpSelectedImg.GetHeight(); j++) { dc.Ge...
