Methods
Alpha (extends w As Window / RectControl, Assigns Value As Integer) / As Integer
Sets the transparency value of a Window or a RectControl to a value similar to a Xojo Color Alpha value. Works like a property, which means both is valid:
Dim Alpha As Integer = Window1.Alpha
Canvas1.Alpha = 230
AlternateImage(extends As PushButton / RadioButton, assigns pic As Picture)
An alternate image that appears on the button when the button is in an on state. Example:
me.AlternativeImage = myPicture
AlternateTemplate(extends As PushButton / RadioButton, assigns pic As Picture)
Like alternate image, but the template representation of the image is used. Example:
me.AlternativeTemplate = myPicture
AlternateTitle(extends b As PushButton / RadioButton, assigns value As String) / As String
The title that the button displays when the button is in an on state. Works like a property, which means from inside a pusbutton:
me.AlternateTitle = "Systems online"
Dim s as String = me.AlternateTitle
BringToFront (extends w As Window) [mac + win]
mac + win]Brings a window to the foreground.
Content (extends p As Popupmenu, Index As Integer, assigns value As ContainerControl)
Assigns an containercontrol as a contentview to the item at the specified index of a popupmenu. Reset to normal cell by assigning Nil.
Draw(extends p As Picture, optional g As Graphics, x As Double, y As Double, width As Double, height As Double, x1 As Double = 0, y1 As Double = 0, sourceWidth As Double = -1, sourceHeight As Double = -1, Operation as NSCompositingOperation = NSCompositingOperation.clear, Opacity as Double = 1
Draws the picture in the specified rectangle of the current CGGraphics context, with optional Blend Modes and opacity. Rest of the parameters are like graphics.DrawPicture. If g is defined, y values are inverted.
DrawAsTemplate(extends p As Picture, optional g As Graphics, x As Double, y As Double, width As Double, height As Double, x1 As Double = 0, y1 As Double = 0, sourceWidth As Double = -1, sourceHeight As Double = -1, Operation as NSCompositingOperation = NSCompositingOperation.clear, Opacity as Double = 1
DrawAsTemplate(extends p As Picture, x As Double, y As Double, width As Double, height As Double)
Like Picture.Draw in this mpdule, except for that the template representation of the picture is being used.
Image(extends s As MenuItem, Scaling As NSImagescaling = NSImagescaling.none, Position As NSCellImageposition = NSCellImageposition.imageleft, assigns Pic As Picture)
The image that appears on the menuitem when it’s in an off state, or nil if there should be no such image.
Image(extends p As PopupMenu, Index As Integer, Scaling As AppkitAddition.NSImageScaling = AppkitAddition.NSImageScaling.None, Position As AppkitAddition.NSCellImagePosition = AppkitAddition.NSCellImagePosition.ImageLeft, assigns value As Picture)
Assigns an image to item at index of a popupmenu.
Image(extends s As PushButton / RadioButton, scaling As NSImageScaling = NSImageScaling.None, position As NSCellImageposition = NSCellImageposition.imageleft, assigns pic As Picture) [mac + win]
[mac + win]Sets the image that appears on the button when it’s in an off state, or nil if there is no such image.
This currently crashes the project under Windows silently when an image or template is assigned second time to a button – because of getting its handle, not because of the declare.
Image(extends s As SegmentedControl, Index as integer, scaling as NSImageScaling = NSImagescaling.ProportionallyUpOrDown, assigns pic As Picture)
Sets the image of a segment to pic, using the specified scaling method.
ImageHugsTitle(extends b As PushButton / RadioButton, assigns value As Boolean) / As Boolean
A Boolean value that determines how the button’s image and title are positioned together within the button bezel. Available since macOS 10.12.
me.ImageHugsTitle = True"
Dim b as Boolean = me.ImageHugsTitle
ImagePosition(extends b As PushButton / Radiobutton, assigns value As NSCellImagePosition) / As NSCellImagePosition
Determines how image and title are placed inside a button cell.
me.ImagePosition = AppKitAddition.NSCellImagePosition.ImageLeft
Dim p as AppKitAddition.NSCellImagePosition = me.ImagePosition
Images(extends parent As Menuitem, s As Menuitem, assigns pics() As Picture) [mac + win]
[mac + win]Sets the offstate and onstate images for a menuitem. Here for compatibility with the Windows equivalent.
ImageScaling(extends b As PushButton / RadioButton, assigns value As NSImageScaling) / As NSImageScaling
The scaling mode applied to make the cell’s image fit the frame of the image view.
me.ImageScaling = AppKitAddition.NSImageScaling.None
Dim s as AppKitAddition.NSImageScaling = me.ImageScaling
MixedStateImage(extends s As MenuItem, assigns Pic As Picture)
The image of the menuitem that indicates a "mixed” state.
SizeToFit(extends r As RectControl)
Resizes a control to the size accomodating its content, if possible.
Style(extends p As PopupMenu, Assigns value As AppKitAddition.PopupMenuStyle) / As AppKitAddition.PopupMenuStyle
Gets/sets the style of a popupmenu.
Template(extends s As PushButton, scaling As NSImageScaling = NSImageScaling.ProportionallyUpOrDown, position As NSCellImageposition = NSCellImageposition.imageleft, assigns pic As Picture) [mac + win]
[mac + win]Identical to Image, only that here the template representation of the image is being used. (on Windows the ICON handle if possible)
This currently crashes the project under Windows silently when an image or template is assigned second time to a button – because of getting its handle, not because of the declare.
Template(extends s As SegmentedControl, Index as integer, scaling as NSImageScaling = NSImagescaling.ProportionallyUpOrDown, assigns pic As Picture)
Identical to Image, only that here the template representation of the image is being used.
