You genius! Thanks.

Hi, I added the following code to the minimal sample: wxSplitterWindow *splitter = new wxSplitterWindow(this, -1, wxDefaultPosition, wxDefaultSize, wxTAB_TRAVERSAL); splitter->SetSize(GetClientSize()); splitter->SetSashGravity(1.0); wxButton* aboutBtn = new wxButton(splitter, wxID_ANY, "About"); wxS...

Aah! Thanks.

Just digging into the code for wxGenericDirCtrl, and it doesn't seem to be consistent with adding its \ to the end of the paths. Sorted now.

Hi, I am surprised to find that wxFileName::AppendDir() and wxFileName::PrependDir() seem to do the same thing. The following code: wxFileName pathApp("C:\Code"); wxFileName pathPre("C:\Code"); pathApp.AppendDir("Project"); cout << "Append = " << pathApp.GetFullPath() << endl; pathPre.PrependDir("Pr...

eranon,

Sure, I can write my own function with the same name etc., but I cannot override it, in the sense that other functions of the base class will still call the original function, and will not call my new one. For those functions to call my new code will require a virtual function.

Hi ONEEYEMAN, I'm surprised, since many of the questions I see in this forum seem to be along similar lines, about modifying the behaviour of wx classes. Indeed, the description of this forum: Are you writing your own components and need help with how to set them up or have questions about the compo...

Hi, I'd like to modify the way wxGenericDirCtrl behaves. Specifically, I'd like the option to sort directories by date, rather than alphabetically. I have tried to inherit from it, so that I can overload ExpandDir() (which is virtual, so I guess it's designed to be overloaded), and have it call a di...

Hi ONEEYEMAN,

I have cloned the git repository, modified the code and created a patch. I will now submit this patch using trac.

Thanks

Hi PB,

Can we at least agree on one thing, that the code in gifdecode.cpp is actively changing one of the colors in the image, and that it is this code that is responsible for the pink colour I am seeing?

Hi PB,

I tried using wxIMAGE_QUALITY_HIGH, but the results still show pink leakage.

Hi PB

> I have no idea why this happens and cannot allocate more time to investigate.

Well, my modifications to gifdecod.cpp seem to fix this problem. Do you think I should suggest this as a modification?

Furthermore, two other applications agree with me. This is another image browser, ACDSee. It draws the GIFs correctly, without any pink: ACDSee.png And this is Paint Shop Pro: PSP.png Would you at least agree with me that adding the pink colour is not standard, and that there are applications which ...

Hi PB, Thanks for being patient with me. :) The application I'm making is an image browser. It shows thumbnails of the images in a directory. Here are some screenshots of my application so far: This is what I started with: Pink_Unmasked.png So I tried setting useMask=true, but that still shows lots ...

There's another reason why the code shouldn't really be changing the colours. Look what happens when my application creates a thumbnail of a GIF that contains transparency information. cats_rescaled.png if (image.LoadFile(fullPath.GetFullPath())) { wxSize newSize = GetTnImageSize(image.GetSize(), si...

Hi PB, Perhaps I'm failing to communicate my needs, or perhaps I'm being very thick. What I want to do is draw this GIF, so that it looks exactly like this: cat_no_transparency_info.gif Shouldn't the code be more like this: transparent = GetTransparentColourIndex(frame); // set transparent colour ma...
