How can I support drag-and-drop in a reparenting window manager?
It looks like if I use an application which supports it, like thunar, and I drag it from one client to another it just goes back. I think this is because it tries to drag it into the frame window. What must I support for this to work properly? EWMH _NET_CLIENT_LIST was my first guess, and I will implement that soon, but I don't see how that will help locate the window it is being dragged to.
Man, reparenting can be a pain! It's just one person answering by now, sorry for all the questions ;)

I was wondering, would it be possible to create a small piece of software that would allow the user to minimize a window by scrolling down on it? (on the top part that can be used to move it via drag and drop, obviously).
Following the same idea, it would be cool to be able to scroll up on the task bar icons to restore a minimized windows. I thought it would be cool (and since the user does not actually click but scrolls instead, it would prevent accidental nearby program openings when trying to restore a window)!
I am a total newbie when it comes to things like these. Could you please indicate me:
if Windows would let me do that (I doubt it wouldn't)?
How to code something like that (what language, and so on...)?
A way of doing this for maximizing the tabs open in the taskbar would be to create a custom taskbar identical to that of the main one. The second taskbar from Dual Monitor Taskbar works this way. There are also libraries in languages such as C++ which can detect scroll wheel movements.
Although this wasn't the most helpful answer, hopefully this could give you some ideas.
It is definitely possible. I found a software that does that 6 years ago and I have been using it ever since. It is called Preme for windows (http://www.premeforwindows.com/)
I have been using the software for about 6 years now and I cannot use windows without it. It also allows closing windows when clicking the mouse scroll key and maximizing a window with scroll up.
I hope this helps you. I am always wondering why Microsoft does have these options built in in the OS!!
I have a friend who's working at a company that offers pretty poor support for its developers (scoring a 1/12 on the Joel Test).
Their build process is locked down pretty tight, and depending on the size of project it could take 40+(x2) mouse clicks to deploy. So I thought, "Hey, why not automate it the clicks using the win32api?" (Specifically using Python). I've got him a real nice tool that works just fine except for one issue - the tool that they use has a navigation pane that may or may not be open.
You can open and close it with a button press, but I'm not sure how I could make sure it was either open or closed. It's irrelevant to the build process - the only problem is that it alters where the mouse needs to click on the screen depending on its open status. The application is written in .NET and it exposes a function call that applications are able to use to toggle the panel, so I've been looking around for ideas and so far I've got two of them:
Attach to the process via a debugger and execute the function call somehow.
Take a screenshot at the location of the panels titlebar (which I've got through the win32 API and doesn't appear to change regardless if the panel is hidden or not).
Is there an easier way to figure out the state of this panel? The developers are given an admin account on their machine in addition to their regular account, so I can entertain ideas that require admin access, though I don't think that should be necessary?
UPDATE:
It looks like there's a button that can close the pane. In UIAVerify something shows up as "text" "Navigation" "btnClose". It says its AutomationId is btnClose but it's a ControlType.Text
What technology is this panel built from? Is it standard GDI or WPF? If its GDI, it should have a HWND. You should be able to find this HWND through either a class name or window title. Once you have the HWND, you can get its width.
If its built with WPF, er, I have no idea, but Snoop does this kind of thing, so I know its possible.
I'd like to make an application which user can drag and drop tab to make a new window contains
a tab control user holds. What i am looking for is the exact same functionality of Google
Chrome browser for window and Internet explorer 9. Both Applications create a new window if
if user drags and drop a tab out of original window. and vice versa.
How do i do this? Any advice or sample code will be appreciated
It's not a simple task, but if you work through it bit by bit...
Most tab controls will allow you to detect mousedown (and maybe even drag) and when the cursor is moved away from the tab row, you create a new window with a single tab (and maybe a frame depending on what you want).
When they drop, show the rest of the frame as required.
As for moving the content, this depends on your application layout but it can be as simple as changing the container of a control (SetParent()) or the destination of a render.
You can also just drag an "image" of the tab and only create the window when they drop.
Getting any more detail than this is going to be preety much impossible without specifics (and you actually accept an answer).
I have a desktop application written in Ruby that is using GTK2. It's just a small test application to play with GTK2, but I'm having problems achieving what I want to do. Is there any way using GTK2 to get at the titlebar (apart from setting the title), specifically to either add a button to it (beside the min/max/etc, B in the below diagram) or to add an option to the menu that pops up when you click the icon on the titlebar (A in the below diagram)?
I'm thinking there might not be because GTK is meant to work with many many different window managers, but I just wondered if there was. As a side question, what event does clicking the 'cross' button fire? At the moment if the user clicks that the window disappears but the program doesn't end - I need to capture that event and quit the program.
Thanks for any help, including hitting me over the head and telling me how silly I am.
Note that this is possible in GTK 3.10 and up, by using gtk_window_set_titlebar(). It replaces the window manager's title bar with a custom one. GtkHeaderBar is a good custom title bar class to use.
You can't, however, make it look just like the window manager would, because you won't know which window manager the user is running.
No, the title bar is owned by the window manager and you will typically not have direct access to it.
When the user tries to close the window by clicking the window manager's button, the window will receive the delete event.
I need to host my window upon a window of another application.
How to enumerate windows of another Cocoa application? Is it possible to control
them?
If no: how can I draw upon a window of another application?
Thanks!
How to enumerate windows of another Cocoa application?
You can enumerate the windows of another application using the Accessibility API. It doesn't matter whether that application is Cocoa or not.
Is it possible to control them?
Here, it does matter, indirectly, whether the application is Cocoa (or Carbon using standard controls). More precisely, it matters whether the application is accessible.
It usually is possible to move another window, resize it, or do simple things with controls in it (such as press buttons).
It is not possible to tape one of your windows to a window in another application. You will have to observe its location and move your window when the other moves. Following a live drag this way is not possible.
If no: how can I draw upon a window of another application?
You can't. You can only draw in your own windows.
You can make a transparent overlay window and draw on that, but that gets you back to the problem of taping one of your windows to a window in another application.
You should probably ask a broader question about whatever it is you hope to achieve by taping one of your windows to a window in another application or by drawing into a window in another application.
Checkout CGWindow.h
CGWindowListCreateDescriptionFromArray() is probably what you're looking for.
Cocoa does not support reparenting of another application window, or drawing on it.
But, there're two ways to get windows attributes for all the applications, like position, size, z-order, etc.
Accessibility API (also allows to control a foreign application window: move, resize, press buttons on it, etc.). If a foreign application does not support Accessibility API, then...
