How can I flip coordinate of cocoa

Hi,
is there a way to flip the coordinate on a cocoa window, to have the start point in the upper right corner instead of lower corner?

Never tried it, but as far as I know you have to change the origin of the window's view with setBoundsOrigin.
However, if you place ui children based from the new 0,0 location they will be invisible if you use positive numbers.
This is because they are placed in the quadrant that is outside the window.
Bottom line: all ui children need to be placed with negative coordinates in order to be visible.
Hope I'm not too far off with my assumption...

Do you only want to flip the y coordinate or both x and y ?
To do both, you could rotate things
Code: Select all
If OpenWindow(0, 0, 0, 222, 200, "ButtonGadgets", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
ButtonGadget(0, 10, 10, 200, 20, "Standard Button")
ButtonGadget(1, 10, 40, 200, 20, "Left Button", #PB_Button_Left)
ButtonGadget(2, 10, 70, 200, 20, "Right Button", #PB_Button_Right)
ButtonGadget(3, 10,100, 200, 60, "Multiline Button (longer text gets automatically wrapped)", #PB_Button_MultiLine)
ButtonGadget(4, 10,170, 200, 20, "Toggle Button", #PB_Button_Toggle)
ContentView = CocoaMessage(0, WindowID(0), "contentView")
Rotation.CGFloat = 180
CocoaMessage(0, ContentView, "setBoundsRotation:@", @Rotation)
Origin.CGPoint\x = WindowWidth(0)
Origin\y = WindowHeight(0)
CocoaMessage(0, ContentView, "setBoundsOrigin:@", @Origin)
Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow
EndIf

The NSView class has a method named isFlipped
You can overwrite this method and return #True .
Is that what you are looking for ?

Hi Wilbert,
isFliped is Deprecated since 10.6 maybe drawInRect:fromRect:operation:fraction:respectFlipped:hints: is the better way.
I will try it in a few days.
Thanks!

Where does it say it is deprecated ?
The Apple docs don't seem to mention that
https://developer.apple.com/documentati ... -isflipped

In my 10.7 DocSet.
Maybe they recant it.

Are you sure you didn’t look at NSImage instead of NSView ?
For NSImage isFlipped is marked deprecated.
