zig 0.14:

- if sliceAsBytes/bytesAsSlice includes sentinel, then need to update our use

- if @src() gained a module field, then include it in the hash

check zig std lib for bytesAsSlice alignment - should it always aligncast?

doc comments and publish

update web-test and publish

redo screenshot

need to copy back out pixels from render targets to normal textures

make simple plot with option to save the image

- save to file on desktop, save to dataurl on web?

tooltips

need a way to get a string description of a keybind to display to user

alignment widget adds margin, but maybe should add a spacer instead?

- see if that makes the Text Entry example settle better

overhaul path construction so we don't maintain an implicit path

make textureCreate* properly return errors

can we save rendering commands and render to a texture we can get back?

- that would help plotting

- could make the demoButton's contents be static (cached images)

if (try dvui.button(@src(), "Export Texture", .{}, .{})) {

// set that texture as the target

_ = Backend.c.SDL_SetRenderTarget(backend.renderer, @ptrCast(G.tex));

// target back to screen

defer _ = Backend.c.SDL_SetRenderTarget(backend.renderer, null);

const pixels = try gpa.alloc(u8, dim * dim * 4);

defer gpa.free(pixels);

_ = Backend.c.SDL_RenderReadPixels(backend.renderer, null, 0, pixels.ptr, dim * 4);

var out_len: c_int = undefined;

const png_data = dvui.c.stbi_write_png_to_mem(pixels.ptr, dim * 4, dim, dim, 4, &out_len);

defer dvui.c.free(png_data);

var png_slice: []u8 = undefined;

png_slice.ptr = png_data;

png_slice.len = @intCast(out_len);

// base64 encode

const b64_encoder = std.base64.standard.Encoder;

const prefix = "data:image/png;base64,";

const encoded_size = prefix.len + b64_encoder.calcSize(@intCast(out_len));

var encoded = try gpa.alloc(u8, encoded_size);

encoded[0..prefix.len].* = prefix.*;

defer gpa.free(encoded);

_ = b64_encoder.encode(encoded[prefix.len..], png_slice);

//std.debug.print("output {s}\n", .{encoded});

//try dvui.openURL(encoded);

}

should do tabIndexSet if the element has size, so even if it's scrolled off the screen we still go to it

- when we do tabIndexNext/Prev it should focus that element and then also send a scroll_to message from that widget - how?

scrollContainer:

- doesn't do multiple widgets going horizontally

- rectFor or minSizeForChild

- add a direction to scrollContainer that controls the direction widgets are added in

lock_visible

- also take into account any viewport movement that frame from events/velocity

do some profiling of the scrolling demo and add caching to BoxWidget?

- add some profiling infrastructure?

- if cache is true and we are outside clipping rectangle, then can skip children and just go again with our minSize

add Options.id_override to forcefully set the id

- use in textEntryNumber

- use in reroder so things don't reset when they get dragged/dropped

- search for all uses of extendId

textLayout:

- check that min width/height works when there are top corner widgets (top left, top right, both) but no text

try to decouple background from border

consolidate touch editing selection

raylib backend

- directly call glfw.waitEventsTimeout?

- events

- instead of useTex, preload (or use raylib's) a 1x1 white texture

- use raylib's default shader (have to give up premultiplied alpha)

- on mac, two-finger scrolling in the demo window a lot hangs?

- enable by default

new theme fields

build needs an option to select backend?

touch dragging should probably not work when the size of the stuff inside the scroll area is less than the scroll area's size?

- otherwise you get lots of meaningless off-the-edge scrolling

README needs a section on themes

- and how the new fields interact

maybe toasts subwindow need some kind of outline?

test ability to scroll_drag on a touch screen - do we need a curtain area around the edge of the scrollarea/screen where touch events will cause a scroll drag?

web backend

- on phone chrome entering characters works, but backspace first removes characters from the keyboard buffer before we get them removed, something to do with IME

web backend clipboard

- ideally we should preventDefault on copy/paste events, then be able to access the clipboard

navigator.clipboard.readText().then(function (text) {

console.log("read: " + text);

});

maybe expand should be a f32 instead of bool

- could express "want this to take up 1/3 of the space"

- could function as weights for BoxWidget

text rendering:

- investigate if with stb_truetype we can align horizontally to pixels?

- see if the vertical weirdness is global, maybe a canvas size thing? Does it happen in the SDL demo?

add cursors to examples (row of buttons or something one for each cursor)

touch editing - when a paste or text insertion happens, toggle off the touch editing

on hidpi display, selecting a bunch of text leaves small gaps noticeable in the selection background

- only if the text is added char by char

paned should have an "autopos" mode where when not collapsed it will use the expand of the children to determine split

- this way you can have the split automatically be not 50/50

need a button for sizing/rotation for icon and raster that works continuously while you hold it down

- add option to Button where when in the down position it keeps refreshing

when new events come in, we assign the focus id, but probably shouldn't once we see a focus mouse event

need a strategy for activating paste from a menu, because the widget will lose focus when the menu is activated

- when the menu gets focus, maybe it saves the previous focus id?

- then when the paste menu item is clicked, it can send focus back to saved id

- also need to synthesize an event so that widget processes a paste

add inertia to scrolling

- if the scrollContainer has more intertia scrolling to do, then it should eat all pointer events, because we don't want any pointer events going to children if the scrolling is still happening

switch from my freetype fork to Mach's

maybe builtin button should record multiple clicks?

- helps in low framerate situations

TextLayout support for large documents

- need a function to say "we are skipping a bunch of bytes" (might be useful for code folding as well)

- addTextDone needs to not always set cursor because there might be lots of text remaining that we aren't rendering

add alpha to Options as well and multiply it by the theme alpha

add backend function to allow screensaver

Tooltips:

- wrapper around thing you want the tooltip for

- floating windows similar to popup

- popup has 3-4 states:

- ready (on first frame where the mouse pointer is above the rect, go to

showing)

- timer (could go here and wait for timer)

- showing (tooltip popup shows, go to off if the mouse pointer is not

above rect)

- off (go to ready on a frame where the mouse pointer is off our rect)

var ttw = ToolTipWidget.init...

- if (ttw.active()) |p| {

// p is the point of the mouse when the tooltip was activated

var ttp = TooltipPopupWidget.init... (pass in TooltipWidget's screenrect, optionally previous ttp if nested)

// ttp

ttp.install();

// tooltip contents

ttp.deinit();

// ttp.deinit() checks:

- if we have a live nested ttp, we stay alive

- if the current mouse pointer is not above ttp OR the passed in ttw screenrect, we stay alive

- if staying alive and we have a ttp parent, tell that parent we are live

}

xstart and ystart for textSize

kerning

when we have a widget that has captured the mouse, need to capture the mouse in the underlying window system so click-dragging works even when the mouse pointer goes outside the window
