[fpc-pascal] First Version Vector Toolkit in OpenGL
You might have read in my prior message to this group my announcement of a vector graphics and physics library I've been writing for FPC. In this first release, I am taking a stab at designing a new user interface toolkit from scratch based on the vector graphics library rendered purely in OpenGL. Below is a video of my first test of this toolkit and I thought I'd share. Perhaps some of you may have some suggestions. https://streamable.com/n42kll Please bear in mind, this is meant to be a VERY minimal toolkit for the purpose of configuring or inputting settings in either game like programs or physics simulation programs. It includes a limited set of controls: windows, panels, sliders, push buttons, glyph buttons, check boxes, text entry, labels, image, and one custom paint control where you can draw whatever you want. That said, everything is fully themeable and you can write or switch to different themes. The theme system manages the size of each control element, their visual representation, and the fonts and colors. It operates completely independent of the controls. Layout is handled for you automatically by the container controls, window or panel, where children can be tiled horizontally, or vertically and placed near, center or far. Each control can have custom margins and containers can have custom size borders (space between controls and their four edges). As mentioned before, this library will be released to a git repository soon with a FOSS license. It will be able to run on Windows, Mac, Linux, and Pi including the new Pi Zero 2 W. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

What confused me is that it's a command line option instead of a mode switch like other language features.

An open question I have with OpenGL based UI libraries is how (or if) composting happens. For example, are you rendering an entire window to a frame buffer and then updating that when one of the controls requests changes, or are you just drawing the entire window and controls every frame? I made a similar UI library which is loosely based on Cocoa but I didn't use any compositing so the entire window needs to redraw itself each frame. This is good enough for basic UI's in games but it's terribly inefficient so I wanted to tackle the problem of a composition layer (frame buffer) which updates only when controls request it and update only that portion of the window.

Re: [fpc-pascal] First Version Vector Toolkit in OpenGL
That's a very good question Ryan. The short answer is this library draws everything each frame. It's meant for writing, games, physics simulations, or drawing animated demos. It runs as fast as you let it go, much like a game program. BUT It includes the ability to easily create and manage render buffers objects. These render buffers allow you to draw to a buffer, then just display the same buffer repeatedly, where you can change it only when needed. This is like the composting system you mention, but it's an opt in feature. The curtains demo linked in my OP is using a render buffer. If I didn't slow it down it would render instantly and there would be no fun watching it draw updates. Additionally, there is a fixed step logic method meant for game or simulation logic that is always invoked at every 1/120 of a second. This ensures simulation logic returns the same results regardless of computing or video render speed. And finally, regarding compositing, the Canvas interface has a set of modes determining how pixels are combined when new pixels are added. These modes can do things like produce a negative image, lighten or darken, multiply pixels, apply masks, and other things. They are like layer modes in Gimp or Photoshop. Oh and I almost forget. You can adjust the vsync or turn it on/off in my library, allowing you more control over CPU / GPU resource usage. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

This is fixed in latest trunk and in the fixes_3_2 branch. You might be able to also work around it on 3.2.2 by adding CROSSOPT="-k-ios_simulator_version_min -9.0" to the make command line, and also add those parameters when compiling a program for the iphonesim target.
