ComboBox background colour

General
1

Is there a way to change the Combobox background colour?

A declare for OSX would be fine. :wink:

2

Sub Open()
dim n as NSComboBoxMBS = me.NSComboBoxMBS

n.drawsBackground = true
n.backgroundColor = NSColorMBS.redColor

End Sub

in the open event of Combobox control.

This will make it red
 if you need a different color, look at the reference for NSColor.

[code] declare function cell lib “Cocoa” selector “cell” (obj as ptr) as ptr
declare sub setBackgroundColor lib “Cocoa” selector “setBackgroundColor:” (obj as ptr, color as ptr)
soft declare function NSClassFromString lib “Cocoa” (classname as CFStringRef) as ptr
soft declare function redColor lib “Cocoa” selector “redColor” (obj as ptr) as ptr

dim red as ptr=redColor(NSClassFromString(“NSColor”))
setBackgroundColor(cell(ptr(me.Handle)), red)[/code]

or

me.nsComboBoxMBS.drawsBackground=true
me.nsComboBoxMBS.backgroundColor=NSColorMBS.grayColor
me.nsComboBoxMBS.textColor= NSColorMBS.whiteColor
me.nsComboBoxMBS.Bordered=true

5

Is there also a way to remove the up and down arrows at the right?

With the NSPopupmenu this is possible by using the setArrowPosition, but the ComboBox does not have this property (so it seems).

More legibly (than my first post) via declares, for the interested


[code]declare function NSClassFromString lib “Cocoa” (classname as CFStringRef) as ptr
declare function whiteColor lib “Cocoa” selector “whiteColor” (obj as ptr) as ptr
declare function grayColor lib “Cocoa” selector “grayColor” (obj as ptr) as ptr
declare sub setBackgroundColor lib “Cocoa” selector “setBackgroundColor:” (obj as ptr, color as ptr)
declare sub setTextColor lib “Cocoa” selector “setTextColor:” (obj as ptr, color as ptr)
declare sub setDrawsBackground lib “Cocoa” selector “setDrawsBackground:” (obj as ptr, value as Boolean)
declare sub setButtonBordered lib “Cocoa” selector “setButtonBordered:” (obj as ptr, value as Boolean)

dim white as ptr=whiteColor(NSClassFromString(“NSColor”))
dim gray As ptr=grayColor(NSClassFromString(“NSColor”))
dim mcell as ptr=ptr(me.Handle)

setDrawsBackground(mcell,true)
setBackgroundColor(mcell, gray)
setTextColor(mcell,white)
setButtonBordered(mcell,true)[/code]

To remove the arrow, I think you’d have to dig into the control and subviews
 not sure how a combobox fits together beyond the control/cell level

If I have a color in Xojo, like &cE6E6E6, how would I make it a NSColorMBS? How do I make a Xojo Color into a NSCColorMBS?

Am I understandable? I do have user defined color values for setting the background color of textfields etc. I would like to have the same color as a background of comboboxes (OSX). I need a way to take that user defined color value and make it a NSColorMBS.

Assuming
dim thecolor as color=&cE6E6E6

Here’s the declare way


[code] declare function NSClassFromString lib “Cocoa” (classname as CFStringRef) as ptr
declare function colorWithSRGBRedgreenbluealpha lib “Cocoa” selector “colorWithSRGBRed:green:blue:alpha:”_
(obj as ptr, red as single,green as single,blue as single,alpha as single) as ptr

dim otherColor as ptr=colorWithSRGBRedgreenbluealpha(NSClassFromString(“NSColor”),thecolor.red/255,thecolor.green/255,thecolor.blue/255,1)
[/code]

MBS:

dim c As NSColorMBS=NSColorMBS.colorWithDeviceRGB(thecolor.red/255,thecolor.green/255,thecolor.blue/255)

Great! It worked! Thanks, Jim!

dim n as NSComboBoxMBS = me.NSComboBoxMBS

n.drawsBackground = true
n.backgroundColor = NSColorMBS.redColor

or this code

me.nsComboBoxMBS.drawsBackground=true
me.nsComboBoxMBS.backgroundColor=NSColorMBS.grayColor
me.nsComboBoxMBS.textColor= NSColorMBS.whiteColor
me.nsComboBoxMBS.Bordered=true
