wxColour - Getting details from a named colour

BlitzMax Forums/Brucey's Modules/wxColour - Getting details from a named colour

Local tp:wxColour = New wxColour.Create( 0, 0, 0 )
tp.SetAsNamedColour( "GREY" )
Print tp.Red()
Print tp.GetAsString( wxC2S_HTML_SYNTAX )
End

I'm trying to retrieve the component r,g,b values from the "GREY" named colour, but am getting back nothing.

I tried this as well:

Local tp:wxColour = New wxColour.CreateNamedColour( "GREY" )
Print tp.Red()
print tp.GetAsString( wxC2S_HTML_SYNTAX )
End

Still nothing...
What am I doing wrong here?

Hmmm. This works - but there's not a wxGrey() defined so I guess that's no help!

        Local tp:wxColour = wxRED()
	Print tp.Red()
	Print tp.Green()
	Print tp.Blue()

[edit] but there is a wxLIGHT_GREY()!

Thanks for the help. The wxRED() works as you said, but when I tried the wxLIGHT_GREY() instead of wxRED() that returns 0's.

Theoretically this should work as I use the following line in my program:

	AuiManager.GetArtProvider().SetColour( wxAUI_DOCKART_BACKGROUND_COLOUR, New wxColour.CreateNamedColour( "LIGHT GREY" ) )

and this sets the colour to "LIGHT GREY" correctly. I can't seem to get the r,g,b values of this "LIGHT GREY" though, no matter what I try. I'm probably screeching at the monitor and pounding the keyboard with bananas again though.

Really? When I do this:

Print wxLIGHT_GREY().Red()	
Print wxLIGHT_GREY().Green()	
Print wxLIGHT_GREY().Blue()

I get:

192
192
192

This works :

SuperStrict
 
Framework wx.wxApp
Import BRL.StandardIO
 
New MyApp.Run()
 
Type MyApp Extends wxApp

	Method OnInit:Int()
	
		Local tp:wxColour = New wxColour.CreateNamedColour( "GREY" )
		Print "ok : " + tp.IsOK()
		
		Print tp.Red()
		Print tp.Green()
		Print tp.Blue()
 
		Return False
	End Method

End Type

This doesn't :

Framework wx.wxApp
Import BRL.StandardIO

Local tp:wxColour = New wxColour.CreateNamedColour( "GREY" )
Print "ok : " + tp.IsOK()

Print tp.Red()
Print tp.Green()
Print tp.Blue()

wxWidgets requires to be initialised properly, which is usually done through the wxApp instance.

It's a bit like how, under-the-hood, BlitzMax kicks off with it's own internal initialization routines - which you don't usually see unless you are hacking with the modules.

Okay, thx Brucey. That works. I understand now.

Thanks for all the help DavidDC.

I gotta get another coffee.

When wxApp OnInit() returns True, you are actually running inside wxWidget's main-loop.
At this point, your wxMax application is completely event-driven.

There is a sample for running your on main-loop, which requires more management on your end (like ensuring events are passed through etc).

I am using the wxApp OnInit() in my program, but I was doing this test at the beginning outside of that loop.

I'll remember next time.

Thx:)
