I tested compiling on Linux and this is what I found.

My system (Arch Linux) does not supply d_namlen or define _DIRENT_HAVE_D_NAMLEN. There are a few windows-specific calls used:

• GetLogicalDriveStringsA
• GetLogicalDriveStringsA
• GetDriveTypeA

Here are the errors. (warnings ommited)

imgui.h lives in the root of the imgui file structure.

Rather specify the include dir through the build system.

I'm working on a game engine, and I'm already using this file browser to open and save projects and scenes. However, I'd also like to use it for selecting sprites, scripts, etc, but they are only in the Assets folder, so how could I modify it to only search in the Assets folder?

Hi ,

I'm using the extension on Windows , and I get this opening the file dialog : As you can see there's a small alignment problem of the filter that is behind the file list. Anyway thanks for your work ! Until now it's the best file browser for imgui windows users :)

Thanks for sharing your code. I think ImGuiSelectableFlags_PressedOnClick is obsolete (and does not compile with the latest version of ImGUI) and I replaced it with ImGuiSelectableFlags_SelectOnClick but I am not 100% sure.

Not sure what change made this happen but I can't build on Windows anymore with imgui 1.85.

C:\projects\gazebosc-sphaero\ext\ImGui-Addons\FileBrowser\ImGuiFileBrowser.cpp(121,46): error C2589: '(': illegal token on right side of '::' [C:\projects\gazebosc-sphaero\build\gazebosc.vcxproj]

Very much related to #7

I think it can also be fixed by using std::max<float> instead of std::max etc

However it's just a workaround.

Hi there, first, a big thx for this addon to Imgui. Then it seems that there has been a litle change in Imgui, so that your file does not compile anymore with Imgui 1.77. In imgui_internal.h it seems that ImGuiSelectableFlags_PressedOnClick becomes ImGuiSelectableFlags_SelectOnClick . So you have to change accordingly you ImguiFileBrowser.ccp , line 615 . I suppose that this line was in relation with the file filter combobox that seems to work ok.

Here's a simple fix I made. I haven't tested it thoroughly but it seems to have fix the bug.

- new_path = current_path.substr(0, current_path.find("/" + current_dirlist[idx]) + current_dirlist[idx].length() + 2 );
+ {
+     new_path = "";
+     for (auto iter = current_dirlist.begin() + 1; iter != current_dirlist.begin() + idx + 1; ++iter)
+         new_path += *iter + "/";
+ }

Since there was two folders with the same name in the path, if you navigate to the deepest one by clicking on it the current_path.find is going to find the first folder instead.

Example: C:/a/path/to/a/folder

Clicking on the second folder "a" is going to cause the bug. In this case the path is still valid.

Example: C:/app/path/to/a/folder

In that case the new path would be "C:/ap" which does not exist.

It would be great for the SELECT folder option to specify also a file filter, so as to get also the list of those filenames contained in the selected folder. Something like this:

file_dialog.showFileDialog("Select Directory##popup", imgui_addons::ImGuiFileBrowser::DialogMode::SELECT, ImVec2(500,300), ".zip,.tgz", &filelist)

Thanks -R

Hi, i've found a small bug inside the bool validateFile() function, file ImGuiFileBrowser.cpp, line 1055:

std::string file_ext = idx == std::string::npos ? "" : selected_fn.substr(idx, selected_fn.length() - idx);

is returning ".ext"

while in needed the extension without the dot to correctly check, "ext"

so idx+1, in the substring extraction, fix the issue:

std::string file_ext = idx == std::string::npos ? "" : selected_fn.substr(idx+1, selected_fn.length() - idx);

I started to play with the extension but I can see several improvement that could be made. It(s just my point , so it could differs from one to another :)

Here's a Windows 10 file dialog :

The allowed extensions are displayed in a list at the right of the filter in a list after the name filter. So the names that don't corresponding to the extension pattern are not displayed , so not selectable.

Moreover, adding the classical jokers like '*' to the filter could be an improvement, at least for windows users :)

Finally it should be possible to pass a filename as a string to open the save dialog , to allow acting as a 'save as' with a already existing file
