I am trying to pick (retrieve) the pallet from storage using RackPick but when i run the model Rackpick vanishes. You can see the links to the model.

To expand on #Yashars comment: You likely either accidentally ticked the "Ignore" box or (even more likely) toggled the "Visible" switch:
Make sure to not ignore the block and toggle it visible.

As shown in the image below, whenever I run my model, it always tells me that there is an error exists in my model.
enter image description here
But when I turn to the "Problems" window at the bottom of my workspace, it doesn't show any exceptions, and the model also works normally.
enter image description here
I want to know how can I deal with the problem, and is there an error in my model, what may cause such a problem?
These can happen rarely, typically it is not a problem. Try any of these options:
Close the model, then close AnyLogic, then restart and reopen
Delete your Workspace folder (C:/Users/username/.AnyLogicProfessional/Workspace8.8), then restart AnyLogic
Reinstall AnyLogic
Likely the 2nd will help, but try them all
I am making a cross-platform windowing layer. When making window relationship stuffs, I got some trouble on window modality.
I have read the official spec: Application Window Properties, and some related topics like this: X11 modal dialog. It seems not sufficient to only set transient-for, but _NET_WM_STATE_MODAL is also required. So I tried to make small programs that apply this property along with transient-for.
I firstly made the program that create the window using SDL2, and use X11 stuffs using the fetched native window handle. But I did not observe any behavior change after the _NET_WM_STATE_MODAL attribute is set: the transient-for target window is still receiving mouse button events, which is not like a modal-blocked parent window that cannot operated by user.
To avoid potential evil stuffs done by SDL2, I further made the test program using GDK3, which provides ready-to-use wrapper functions. The behavior is same as the SDL2 program.
As I did not observed any change before/after _NET_WM_STATE_MODAL is set, what is the expected behavior of that property?
As I did not observed any change before/after _NET_WM_STATE_MODAL is set, what is the expected behavior of that property?
That's a question we cannot answer. It's a hint for the window manager to indicate modality, but, as in most cases, it is up to the window manager to decide what to do with this hint.
In other words behavior depends entirely upon the window manager and you haven't stated which window manager you were testing with.
Furthermore, this hint requires the window manager to be EWMH-compliant, which not all of them are or aren't fully. You can use _NET_SUPPORTED on the root window to see a list of atoms the window manager claims to support. If _NET_WM_STATE_MODAL isn't listed there, chances are the window manager really doesn't implement this hint at all. If it is listed, the window manager claims to support it, but a) it might be lying (let's not assume that, though) and b) behavior is up to the window manager.
Is there a way to remove only the unselected breakpoints in eclipse?
The reason is so that i could easily remove those breakpoints that i'm not currently involved in.
I don't want to break my flow of concentration with choosing things that aren't near the things i'm concentrating on.
I could just then disable all and select only those that i'm interested in debugging while not forgetting which debugs mattered in this most current problem.
OR...
Is there an invert selection of breakpoints?
There is a 'Breakpoint'-View you could start with ALT+SHIFT+Q,B (or using Window->Show View->Breakpoints).
You can select, activate and even delete All/selected breakpoints.
If you are working at a specific topic, try using MyIyn, as you can even focus your breakpoints on the task you are working at.
Is there any way to track variable changes or memory changes in Xcode? I'm looking for functionality like Visual Studio's data breakpoint.
I want to know where my object's view frame is being changed. I want to set a breakpoint at a member variable and run it. Then I could determine where it's changed.
Xcode uses gdb (or lldb, but that's another story) to implement its debugging functionality. gdb has the ability to set hardware watchpoints and hence so does Xcode.
This is a useful page for generic debugging of memory errors. Xcode's debugging console window is really just a gdb shell, you can type in commands as you please. The ever-helpful Quinn Taylor explains how to do so in this related post.
If you'd rather avoid interacting with gdb directly, you can right-click a variable in Xcode's debugging window and select "Watch Variable". Xcode will then alert you whenever your variable's value has been changed.
You can use hardware watchpoints.
You have to get the address of the variable you want to track (type p &my_var in gdb prompt).
It will print somehting like 0x12345678.
With gdb: type watch *(int *)0x12345678.
With lldb: watch set expression (int *)0x12345678 (or w s e (int *)0x12345678)
This assumes your variable is an int. It will create an hardware watchpoint on this address.
Hope this helps.
Yes.
Under the Run menu there is "Debugger" which provides a visual frontend to gdb.
Also, there is a breakpoint button next to the Build and Run button. You can click that and manage your breakpoints under Run > Manage Breakpoints.
I know this post is old but in case you are still wondering I posted a detailed answer here: In XCode 6 how can you set a watchpoint without stopping execution?
Is there any way to restart a program in Eclipse? (preferably 1-click)
I really wish the console view had something like a restart button that would kill the app and restart it with the latest changes.
This always takes me at least three clicks. I click the down arrow next to the green circle with white triangle (play button) to open the dropdown menu, then I click to choose the Java main that I want to run, and then to stop I click the red square terminate button in the console view. Is there any easier way to do this that requires fewer clicks?
In Eclipse 4.1
open:
windows->Preferences->keys
in the filter text type: terminate and relaunch
In the binding add your binding (i use shift-F5)
For "when" select "In Windows"
This will do it in single shorcut for you.
Or install relaunch plugin:
https://bitbucket.org/mantis78/relaunch-plugin/wiki/Home
which will enable you to restart anywhere
If you use "build automatically", there is a good chance that your changes are applied on the running program, on the fly. As such, most changes will be effective directly without a need to restart.
If there is a structural difference and Eclipse can't inject the new code (for example if you change anonymous classes, or inheritance patterns), then you will be prompted with a dialog inviting you to restart the application in one click:
Exceptions are when you change the value of a static variable (or of the initialization of a class that won't be executed again until you restart the application). In this case indeed, you will need to restart explicitly with another method.
the console view has a terminate button (a red square) which stops the execution. then another click on the Run button (the green circle with triangle) begins execution again.
thats what i do - 2 clicks :)
If you're using Eclipse with Spring you could download the "Spring Tools X" plugin.
This will automatically add a start and relaunch button to the top bar menu.
It should be available on any perspective.
I haven't found an elegant solution for this problem, but if your program is short running and you can live with a few instances here and there, you can just use the run command. Its default shortcut is Ctrl+F11. Every time you press this, your application will restart. BUT! If you press this while your application is still running, another instance will be run because the "old" instance won't be automatically terminated.
There are ways to really terminate your application using shortcut keys, but that requires setting breakpoints and then using the "terminate" command, and that isn't very elegant.
When developing my own network application, I have added a code to check if the older instance is running, and if so, then send an agreed command over network socket for graceful shutdown. While this approach may not be the best as universal solution, it allows clean shutdown of the previous instance, rather than just killing it.
Easy way without plugin, every Eclipse !
Click the project from of this icon at this time hold the shift Button, Project will restart (Terminate and relaunch) with server port also.
