Bug ??? set global property or constant to RGBA

Getting Started
1

I tried experimenting with XOJO color and specifically RGBA to get a property, computed property, or constant.
I get some interesting analyzer errors.
For the constant [quote]App.CRghtColr Declaration
Not enough arguments: got 0, expected 4.
Shared CRghtColr As Color = Color.RGBA(000, 061, 255, 208)[/quote]

For the computed property, the value for get that shows in the top is [quote]&c00000000[/quote].
That is promising but I can’t find a converter of RGBA to hex. I have tried several.

I have tried to find posts that explain, but I can’t find “RGBA property” mentions. It usually shows RGB.

I figured out how to get a full hex value but now I have another error: Syntax error.

Public Const kCRghtColr as Color = #c003dffd0

I don’t understand.

3 
Public Const kCRghtColr as Color = &c003dffd0

Thanks Dave.
Yup. Figured that out. Now for preventing the error

Change Shared to Dim

Dim CRghtColr As Color = Color.RGBA(000, 061, 255, 208)

How do I make it global. Like adding adding a property via the IDE.

I tried this code in an App method

Global CRghtColr As Color = Color.RGBA(000, 061, 255, 208)

I get another syntax error

[quote]App.OpenPrefs, line 8
Syntax error
Global CRghtColr As Color = Color.RGBA(000, 061, 255, 208)[/quote]

And where did you find that syntax? (and the use of “#” for that matter)
Checking the LangRef might save you posting questions with improper use of syntax

I don’t believe that you can declare a global like that.

The easiest way is to create a module then add a property to that module. That property will then be global across your project.

Or a method if you want it to be Read Only.

I get errors if I try to declare an RGBA property. I can’t figure it out. I’ve tried it without parentheses and still some error.

[quote]MnStuff.CRghtCol Declaration
Syntax error
CRghtCol As Color = 000,061,255,208[/quote]

Here you go Arthur:

Oh. You don’t give it values. I can do that? That’s easy.

Why can’t I put values in?

13

If you do this:

Then you can give the color a default value.

14

Could this be a bug?
I wonder what is different. I use the current version on a Mac.

15

Could this be a XOJO bug?

Without

With Default Value

Error message for With

[quote]MnStuff.CRghtColr Declaration
Syntax error
CRghtColr As Color = #c003dffd0[/quote]

You are using # while others in this thread are using &.

I haven’t learn about colors and it’s values, but I guess that could be the problem. Or maybe it needs 4 pairs (8 total after #) and you have 9?

17

&C is the color designator, not #C as has been mentioned numerous times in this topic

I am not embarrassed, but thank you for pointing the error.
If you look up on the internet [quote]#ff0000[/quote] you will find infinite (almost) references to hex value and red.

If you then replace the # with an & the same sites will show up.

I copied the hex value above from w3schoolslink text.com where they represent and apparently most of the internet also represent hex colors with a #. XOJO uses an &

My problem of this bug is solved in that:

  1. XOJO uses different symbols.
  2. The analyzer didn’t point out the expected format for a color.

Arthur, I wouldn’t suggest going on the rest of the internet to find syntax for Xojo command. Check:

http://developer.xojo.com/color

for all the information you need on Color and keep http://developer.xojo.com/ as a goto site for Xojo reference information.

That’s HTML syntax, not Xojo. Different language, different syntax.
