UXOpenPanel

UXOpenPanel is the call an app makes to ask for a file:

u8* path = UXOpenPanel.run((u8*)"Open Image", (u8*)"/home/user");
if (path != (u8*)0) { openDocument(path); }

Where the backend has a native dialog (NSOpenPanel, GetOpenFileName), the driver runs it. Where it doesn’t (GEM), the call falls back to runToolkit, which runs the toolkit-drawn UXFilePanel. Application code sees no difference: a prompt and a start directory go in, and a chosen path comes out.

Topics

run

static u8* run(u8* prompt, u8* startDir)

Runs the dialog modally. Returns a malloc’d path string the caller owns, or null on Cancel.

runToolkit

static u8* runToolkit(u8* prompt, u8* startDir)

The fallback half. You can call it directly (a test drives it on any backend). It constructs a fresh UXFilePanel and runs it.
