dataGetSlice

Retrieve slice contents for key (id+name).

dataSetSlice strips const from the slice type, so always call dataGetSlice with a mutable slice type ([]u8, not []const u8).

Can be called from any thread.

If called from non-GUI thread or outside Window.begin/Window.end, you must pass a pointer to the Window you want to add the value to.

The returned slice points to internal storage, which will be freed after a frame where there is no call to any dataGet/dataSet functions for this key.

The slice will always be valid until the next call to Window.end.

Parameters

win:?*Window: ?*Window
id:Id: Id
name:[]const u8: []const u8
T:type: type

Implementation

pub fn dataGetSlice(win: ?*Window, id: Id, name: []const u8, comptime T: type) ?T {
    return data.getSlice(win, .widget(id, name), T);
}
