 FXRuby thread
#1
Hello everybody,

I no longer have Qt so I'm messing with GUI building applications that are Ruby based. While I do have multiple (experimental prototype) projects in different toolkits (tk, Shoes, TGUI (SFML)), this thread will focus exclusively on FXRuby and whatever related problems I come across.

So right now I'm trying to create an expanded system for Animation effects (think RMVX Ace Database/Animations + some extra features).

The problem I'm having is I can't figure out how to dynamically set dimensions of various widgets such as FXImageView, FXButton, FX... whatever. For some reason, FXMainWindow responds to #width=, #height=, #resize(width, height) but none of the other classes seem to respond to these functions. I would like to micromanage the width and height of all the widgets (buttons, image view, etc) in this frame and ensure that they don't auto-morph. Matter of fact, I'd like the size of the window to not be mouse-adjustable either, I'd like it fixed. I'm understanding that this system does a lot of auto-formatting but sometimes I just want something to be exactly where I want it (x, y) at the exact size I want (width, height).

To install FXRuby do gem install fxruby. This is NOT an RPG Maker script, so Ruby is required to run it.
 
The const ANIMATION_PNG will have to be changed to something on your computer so we have a png graphic to work with.

Things I'm trying to figure out...
  • Change the X, Y, Width and Height of different widgets to desired dimensions.
  • Make FXMainWindow a fixed size. No full screen, no adjusting with mouse.
  • Set a designated application icon.
  • Figure out how to format the table's columns and rows for future use.

Here is an image of what the application currently looks like (WIP). The formatting isn't the greatest, I need to work out all the kinks to make it look prettier.

EDIT: I've updated the code in the post and (here) is a pastebin link if the formatting messes up. IRB still acts like a fool sometimes with error exceptions but I'll figure out a more robust solution later on.

I'm waiting for the "FXRuby : Create Lean and Mean GUIs With Ruby" book to arrive. Until then, I'm just messing with examples and trying to make what I need right away.

So what would usually be considered the "SE and Flash Timing" table, I was going to introduce all of the sprite effects that are already programmed into the Sprite classes, such as appear, vanish, blink, collapse, etc. I also want to trigger Damage Pop (Whole) and Damage Pop (Frac) via the sub-prompt to allow for fine tuned control of damage display. There is a lot more but needless to say this will replace (or extend) the default RPG Maker animation file system with something chunkier and meatier.

I shouldn't even be awake right now, nor should I be bumping this but I've made significant progress. I'm still trying to figure out how to format things the way I want them but here is the latest format...

(Things aren't correctly placed exactly as I want them, some stuff is missing, but this is a work in progress)

If I get comfortable working with this software, I might re-start the ReGaL project. No promises. I have a business to run and life is busy, but I would still like to get back into it. If anything, I'll at least try to finish this widget and I'm sure people could use it to extend their RPG Maker stuff. I don't think the widgets will need to run on the same version of Ruby as RM, nor will anybody need to require the Ruby Gem within their project. We'll see...

I'm sorry to tell you something you might have learned on your own, Kain, but it seems that the Fox Toolkit philosophy behind windows and its components (buttons, boxes, etc.) promotes their adaptability instead of their rigidness. Sad

Plus the contents actually look quite weird if running on Debian, a Linux OS that supports Ruby 2.7 and fxruby 1.6.x. Happy with a sweat
