I am modifying the wxGenericDirCtrl class to add the Windows folders "Desktop", "My Documents", etc., and I would like them to have the correct icons. https://www.howtogeek.com/thumbcache/2/200/0b3d356b62ce7879d34670a33ffa68bf/wp-content/uploads/2011/10/00_explorer_window.png Pre...

Thanks, I'll try that and let you know.

Doublemax, I was thinking that the wxTreeCtrl might be doing that itself, however, mine doesn't. I'm not sure exactly how the treectrl is informed about the dragging. Doesn't it need to be connected to an event or something? Certainly the tree ctrl in my application doesn't do the highlighting. I sh...

Hi Oneeyeman, Thanks for the reply. I have had a good look at the treectrl sample. It does indeed do the highlighting of tree elements as they are dragged over. However, I can't for the life of me see how this is implemented in the code. The code has functions to handle the start and end of the drag...

When I am dragging across a window, what events are called on that window to inform it that a drag is currently underway? When the mouse is simply moving inside a window, I seem to be able to get wxEVT_MOTION events. But when a drag is happening, those events don't seem to be generated. And I can't ...

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&q...

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.GetFu...

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.
