Why would you want to resize external applications?

grabiller · **Posted:** Thu Jul 24, 2014 6:39 am

I found this:
https://github.com/nint22/WindowSnaps/b ... Delegate.m

Seems to do what I'm looking for. I understand part of the code but I have no idea how to transpose that in PB.

Perhaps you (or someone else) can help ? I know it's a lot to ask but I think it would be really neat to have a little cross-platform set of procedures to list, move and resize windows.

I've explained that in my first message, please re-read:

../.. I'm trying to create a tool for an application that uses a lot of popup windows, to automatically arrange/snap/resize them in a clean way. The application is working on Windows & Mac but I only know how to do it on Windows. Would be great to have this tool working also on Mac OSX ../..

The application being Lightwave 3D.

Someone did a tool for that on Windows with AutoIt. Here is the result:

I would like to create something similar, but cross-platform and more advanced.

I'm used to organize gui-apps (in a tile'd way) on linux with OpenBox and some additional keyboard shortcuts.

Because I wanted to have the same on MacOS I searched and found spectacle.
It's opensource and the code is on github.
Maybe the spectacle code can give you an idea how it's done.

Here is the start to enum the windows and get the PID:

Code:

ImportC ""
    CGWindowListCreate(_1, _2)
    CGWindowListCreateDescriptionFromArray(arr)
    CFArrayGetCount(arr)
    CFArrayGetValueAtIndex(arr, index)
    CFRelease(arr)
    CFDictionaryGetValue(_1,_2)
    CFStringCreateWithCharacters(alloc,text.p-Unicode,len)
    CFNumberGetValue(_1,_2,_3)
EndImport


;CFArrayRef
WindowList = CGWindowListCreate(1, 0)
Debug WindowList
DescriptionList = CGWindowListCreateDescriptionFromArray(WindowList)
Debug DescriptionList
Debug "--------------"
If DescriptionList
    count = CFArrayGetCount(DescriptionList)
    If count
        For i = 0 To count-1
            id = CFArrayGetValueAtIndex(DescriptionList,i)
            Debug "ID: "+id
            pid_num = CFDictionaryGetValue(id, CFStringCreateWithCharacters(0,"kCGWindowOwnerPID",17))
            If pid_num
                CFNumberGetValue(pid_num,9,@pid.l)
                Debug "PID: "+pid
            EndIf
        Next
    EndIf
EndIf
CFRelease(DescriptionList)
CFRelease(WindowList)

It is pretty straightforward to translate the code, so I hope you can do the rest yourself. I'm having a beer or two now (after returning from nightshift work),
not in the mood for doing all the work for you. It is boring because PB does not import any of this API functions, but it should be doable.

Press ALT+CMD+ESC to terminate the running processes, if it does not exit correctly (possibly some clean-up missing).

Wouldn't it be better to discuss your problem within a separate topic instead in this topic of general interest?
Maybe a moderator can split it and move grabiller's problems to a separate topic, probably starting at &start=159

Try Cinema4D as a cross-platform alternative. :twisted:

@fsw
Thanks a lot for pointing me to this application, it does exactly what I need, it will surely be helpful.

@Danilo
Thanks a lot. I'm not asking you to "do all the work for me" but at least this example gives me a point to start. I'll see how far I can go from there.

Regarding a separate topic you are right, sorry, if I need more help I'll create a new thread in the Mac section.

ps: What makes you think I need an alternative ? ;-)

Cheers,
Guy.

Getting the portion of the screen in which it is currently safe to draw your application content (i.e. excluding the dock and the top menu):

Code:

OpenWindow(0,0,0,0,0,"test",#PB_Window_SystemMenu|#PB_Window_Invisible)

mainScreen = CocoaMessage(0,0,"NSScreen mainScreen")
CocoaMessage(@visibleFrame.NSRect,mainScreen,"visibleFrame")

Debug visibleFrame\origin\x
Debug visibleFrame\origin\y
Debug visibleFrame\size\height
Debug visibleFrame\size\width

; origin\y starts from the bottom left corner of the screen, so to get the safe coordinates for PB we can calculate it like that:
ExamineDesktops()
winX = visibleFrame\origin\x
winY = DesktopHeight(0)-visibleFrame\size\height-visibleFrame\origin\y
titleBarH = WindowHeight(0,#PB_Window_FrameCoordinate)-WindowHeight(0,#PB_Window_InnerCoordinate)
winMaxW = visibleFrame\size\width
winMaxH = visibleFrame\size\height-titleBarH

Debug winX
Debug winY
Debug winMaxW
Debug winMaxH

ResizeWindow(0,winX,winY,winMaxW,winMaxH)
HideWindow(0,#False)

Repeat : ev = WaitWindowEvent() : Until ev = #PB_Event_CloseWindow

Subclassing a Gadget during runtime. This allows overriding methods for a particular gadget without affecting the others, as shown in the following example.

Code:

ImportC ""
  sel_registerName(STR.p-ascii)
  class_addMethod(class, selector, imp, types.p-ascii)
  objc_allocateClassPair(class, newClassName.p-ascii, extraBytes)
  objc_registerClassPair(class)
  object_setClass(object, class)
EndImport



Procedure SubClassGadget(Gadget, newClassName.s)
  Protected oldclass = CocoaMessage(0, GadgetID(Gadget), "class")
  Protected result = 0
  result = objc_allocateClassPair(oldclass, newClassName, 0)
  objc_registerClassPair(result)
  object_setClass(GadgetID(Gadget), result)
  ProcedureReturn result
EndProcedure

Procedure SubClassWindow(Window, newClassName.s)
  Protected oldclass = CocoaMessage(0, WindowID(Window), "class")
  Protected result = 0
  result = objc_allocateClassPair(oldclass, newClassName, 0)
  objc_registerClassPair(result)
  object_setClass(Window(Window), result)
  ProcedureReturn result
EndProcedure

Procedure CocoaAddMethod(Class, Method.s, CallBack)
  Protected sel = sel_registerName(Method)
  class_addMethod(Class, sel, CallBack, "v@:@")
EndProcedure


ProcedureC EventHandler(sender)
  Debug sender
  Debug "Escape Key Pressed"
EndProcedure



OpenWindow(0, 0, 0, 322, 205, "SubClassing", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
StringGadget(0, 8,  10, 306, 23, "StringGadget (Calls callback on ESC key)")
StringGadget(1, 8,  45, 306, 20, "Second String Gadget")

class = SubClassGadget(0, "MyStringGadget")

CocoaAddMethod(Class, "cancelOperation:", @EventHandler())    

Debug PeekS(CocoaMessage(0, CocoaMessage(0, GadgetID(0), "className"), "UTF8String"), -1, #PB_UTF8)

Repeat 
  event = WaitWindowEvent()
Until event  = #PB_Event_CloseWindow

Edit: Added a function called SubClassWindow() for convenience.

Menu manipulation routines.
Functions to add MenuItems or SubMenus to given MenuTitles (by index) and to remove MenuItems (by handle). Useful for "Recent Files" and correct implementation of the "Window" menu. It's a bit more elegant than deleting and rebuilding the entire menu over and over again.

Code:

Procedure AppendItemToMenu(MenuItemID, Text$, Menu, MenuTitleIndex, ImageID=0)
  Protected mnuArray = MenuID(Menu)
  Protected newParent = CocoaMessage(0, mnuArray, "objectAtIndex:", MenuTitleIndex)
  Protected mItem = MenuItem(MenuItemID, Text$, ImageID)
  Protected oldParent = CocoaMessage(0, mItem, "menu")
  CocoaMessage(0, oldParent, "removeItem:", mItem)
  CocoaMessage(0, newParent, "addItem:", mItem)
  ProcedureReturn mItem
EndProcedure

Procedure AppendSubmenuToMenu(Text$, Menu, MenuTitleIndex, ImageID=0)
  Protected mnuArray = MenuID(Menu)
  Protected newParent = CocoaMessage(0, mnuArray, "objectAtIndex:", MenuTitleIndex)
  Protected mItem = MenuItem(0, Text$, ImageID)
  Protected subMenu = CocoaMessage(0, 0, "NSMenu alloc")
  CocoaMessage(0, subMenu, "initWithTitle:$", @Text$)
  Protected oldParent = CocoaMessage(0, mItem, "menu")
  CocoaMessage(0, oldParent, "removeItem:", mItem)
  CocoaMessage(0, newParent, "addItem:", mItem)
  CocoaMessage(0, mItem, "setSubmenu:", subMenu)
  ProcedureReturn subMenu
EndProcedure


Procedure AppendItemToSubmenu(MenuItemID, Text$, SubMenu, ImageID=0)
  Protected mItem = MenuItem(MenuItemID, Text$, ImageID)
  Protected oldParent = CocoaMessage(0, mItem, "menu")
  CocoaMessage(0, oldParent, "removeItem:", mItem)
  CocoaMessage(0, SubMenu, "addItem:", mItem)
  ProcedureReturn mItem
EndProcedure  

Procedure RemoveMenuItem(MenuItemHandle)
  Protected Parent = CocoaMessage(0, MenuItemHandle, "menu")
  CocoaMessage(0, Parent, "removeItem:", MenuItemHandle)
EndProcedure

; DEMO

OpenWindow(0, 200, 200, 200, 100, "Menu Example")
; create a menu and fill it with two MenuTitles and a few items
CreateMenu(0, WindowID(0)) 
; a file menu
MenuTitle("File")
MenuItem(1, "Open"   +Chr(9)+"Cmd+O")
MenuItem(2, "Save"   +Chr(9)+"Cmd+S")
; an edit menu
MenuTitle("Edit")
MenuItem(4, "Cut")
MenuItem(5, "Copy")
MenuItem(6, "Paste")
delme = MenuItem(7, "Delete me")

; now we append an item to the "File" menu (which is at index 0)
AppendItemToMenu(3, "Save as...", 0, 0)

; and we'll append a submenu to the first (index 0) menu too
sub = AppendSubmenuToMenu("Recent Files", 0, 0)

; our newly created sub menu needs a few items
AppendItemToSubmenu(100, "File number one"  +Chr(9)+"Shift+Cmd+1", sub, 0)
AppendItemToSubmenu(101, "File number two"  +Chr(9)+"Shift+Cmd+2", sub, 0)
AppendItemToSubmenu(102, "File number three"  +Chr(9)+"Shift+Cmd+3", sub, 0)

; get rid of the "delete me" item
RemoveMenuItem(delme)

  TextBlockHeight = Int(Rect\size\height)
  LineHeight = GetLineHeight(EditorGadgetID)

  ProcedureReturn TextBlockHeight / LineHeight
EndProcedure

OpenWindow(0, 200, 100, 300, 210, "EditorGadget")

I posted this example in a bug thread but since those threads can be removed if a bug has been fixed, I'm posting it here also.
It's an example of the AVAudioPlayer class.

Code:

Procedure.i AudioPlayer(FileName.s)
  ProcedureReturn CocoaMessage(0, CocoaMessage(0, 0, "AVAudioPlayer alloc"), 
                               "initWithContentsOfURL:", CocoaMessage(0, 0, "NSURL fileURLWithPath:$", @FileName), 
                               "error:", #Null)
EndProcedure

Procedure SetVolumeAndPan(AudioPlayer.i, Volume.f = 1.0, Pan.f = 0.0)
  CocoaMessage(0, AudioPlayer, "setVolume:@", @Volume)
  CocoaMessage(0, AudioPlayer, "setPan:@", @Pan)
EndProcedure



Define.f LeftAverage, RightAverage, LeftPeak, RightPeak

OpenWindow(0, 0, 0, 270, 70, "AVAudioPlayer example (OSX 10.7+)", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)

Using others code examples from here I thought I'd take a stab at creating a HUD window. At this point it doesn't look too bad but I'm not sure if this is the correct approach or not. Obvious things I'd like to do is to color the Button, Scrollbars, Option Button, and Circular Slider if it's possible, making them look more appropriate for a HUD window. I guess it would be nice to be able to extend existing controls and modify them but I don't think that's possible in PB. I'm also not sure how to trap/respond to the #NSClosableWindowMask i.e. Close Gadget of the HUD Window (which isn't an actual window but an NSPanel object)

Code:

Enumeration CGWindowLevelKey
   #kCGBaseWindowLevelKey = 0
   #kCGMinimumWindowLevelKey
   #kCGDesktopWindowLevelKey
   #kCGBackstopMenuLevelKey
   #kCGNormalWindowLevelKey
   #kCGFloatingWindowLevelKey
   #kCGTornOffMenuWindowLevelKey
   #kCGDockWindowLevelKey
   #kCGMainMenuWindowLevelKey
   #kCGStatusWindowLevelKey
   #kCGModalPanelWindowLevelKey
   #kCGPopUpMenuWindowLevelKey
   #kCGDraggingWindowLevelKey
   #kCGScreenSaverWindowLevelKey
   #kCGMaximumWindowLevelKey
   #kCGOverlayWindowLevelKey
   #kCGHelpWindowLevelKey
   #kCGUtilityWindowLevelKey
   #kCGDesktopIconWindowLevelKey
   #kCGCursorWindowLevelKey

You have to remember that in the beginning of your code example you have opened window w1 and hidden it. When closing the HUD panel you have to also close that hidden window because otherwise your app will not terminate. The End statement in procedure OnBtnClick() is not sufficient. So I would propose to utilize PostEvent(#PB_Event_CloseWindow) to send the close event to your main event loop in order to properly terminate your program when clicking onto the Exit button:

Code:

Procedure OnBtnClick()
  PostEvent(#PB_Event_CloseWindow)
EndProcedure

In order to properly close your program when clicking onto the close button of your HUD panel, I would propose to define a callback for "windowShouldClose:" and attach that method to the NSPanel class:

Code:

ImportC ""
  class_addMethod(Class.I, Selector.I, *Callback, Types.P-ASCII)
  sel_registerName(MethodName.P-ASCII)
EndImport

ProcedureC PanelShouldCloseCallback(Object.I, Selector.I, Sender.I)
  PostEvent(#PB_Event_CloseWindow)
EndProcedure

class_addMethod(CocoaMessage(0, NSPanel, "class"),
  sel_registerName("windowShouldClose:"), @PanelShouldCloseCallback(), "v@:@")
CocoaMessage(0, WindowID(w1), "setDelegate:", AppDelegate)

I have taken your code and integrated my above proposed additions. Now it's possible to terminate your program properly by clicking onto the Exit button or the close button of your HUD panel... :wink:

InputRequester with cancel button and ability to set default text

Code:

Procedure.s InputRequesterEx(Title.s, Info.s, DefaultInput.s = "")
  Protected.i Alert, InputField, Frame.NSRect
  Frame\size\width = 300
  Frame\size\height = 24
  InputField = CocoaMessage(0, CocoaMessage(0, CocoaMessage(0, 0, "NSTextField alloc"), "initWithFrame:@", Frame), "autorelease")
  CocoaMessage(0, InputField, "setStringValue:$", @DefaultInput)
  Alert = CocoaMessage(0, CocoaMessage(0, 0, "NSAlert new"), "autorelease")
  CocoaMessage(0, Alert, "setMessageText:$", @Title)
  CocoaMessage(0, Alert, "setInformativeText:$", @Info)
  CocoaMessage(0, Alert, "addButtonWithTitle:$", @"OK")    
  CocoaMessage(0, Alert, "addButtonWithTitle:$", @"Cancel")

Hi wilbert,
I was looking at your InputRequesterEx() code and thought I would change it to a MessageRequester with up to 5 buttons with text you can change. The left-most button, usually 'Cancel', will always be zero.

[added custom icons to requester]
[added ability to change default button (blue/responds to 'enter')]
[note] I've changed the code and now the 'defaultbutton' can have a value between 1 and 5 and the returned value is between 1 and 5 (reading left to right in message window)

Code:

Global Workspace.i = CocoaMessage(0, 0, "NSWorkspace sharedWorkspace") ; for MessageRequesterEx
Procedure MessageRequesterEx(Title.s, Info.s,type.s="'note'",defaultbutton=1,buttonone.s="Ok",buttontwo.s="",buttonthree.s="",buttonfour.s="",buttonfive.s="") ; max 5 buttons
    Protected.i Alert, Frame.NSRect,numberbuttons=0,button
    If FindString("'APPL''caut''note''stop'",type,1)=0 : Debug "no type":EndIf
    Frame\size\width = 300
    Frame\size\height = 24
    Alert = CocoaMessage(0, CocoaMessage(0, 0, "NSAlert new"), "autorelease")
    CocoaMessage(0, Alert, "setMessageText:$", @Title)
    CocoaMessage(0, Alert, "setInformativeText:$", @Info)
    CocoaMessage(0, Alert, "setIcon:", CocoaMessage(0, Workspace, "iconForFileType:$", @Type))
        
    If buttonfive
        CocoaMessage(0, Alert, "addButtonWithTitle:$", @buttonfive) 
        numberbuttons+1
    EndIf
    If buttonfour
        CocoaMessage(0, Alert, "addButtonWithTitle:$", @buttonfour)
        numberbuttons+1
    EndIf
    If buttonthree
        CocoaMessage(0, Alert, "addButtonWithTitle:$", @buttonthree)
        numberbuttons+1
    EndIf
    If buttontwo
        CocoaMessage(0, Alert, "addButtonWithTitle:$", @buttontwo) 
        numberbuttons+1
    EndIf
    CocoaMessage(0, Alert, "addButtonWithTitle:$", @buttonone)
        Button = CocoaMessage(0, CocoaMessage(0, Alert, "buttons"), "objectAtIndex:",numberbuttons-defaultbutton+1)
        CocoaMessage(0, CocoaMessage(0, Alert, "window"), "setDefaultButtonCell:", CocoaMessage(0, Button ,"cell"))
    ProcedureReturn 1001+numberbuttons-CocoaMessage(0, Alert, "runModal")
EndProcedure
