But maybe someone has code samples of how to convert PDF?
It's been awhile since i used it myself, but if imagemagick supports
reading PDF's this might work:
```
Image pdf = new Image("./test.pdf")

DMagick hasn't been updated in a while so it will probably not work with

This brings debugging with keyboard back to the same speed as with the UI buttons for our application." This seems to be an issue with Gtk. I'm not sure if GtkD can do anything about it. Maybe somehow reroute the keyboard handler(first remove it from the hook then call it manually or reduce the number of calls to it). I can confirm that gtk call "SetWindowsHookEx" with the "WH_KEYBOARD_LL" ID upon initialization. As far as i can tell it doesn't provide a way to skip this. -- Mike Wey

My understanding is this: Returning an object (as opposed to a single value) means returning a pointer rather than the entire object. And the object will cease to exist once the function returns because the scope no longer exists. So, it follows that an out variable passed in will preserve the object itself once program control returns to the caller. While that would be true for things that live on the stack, this is not the case for RGBA. The C version of getRgba uses the "out" parameter so you can pass in a existing GdkRgba, even tough that would make it more like ref. This doesn't make sense for the d binding since you will always get a new RGBA passed through the out parameter. -- Mike Wey

On 19-12-17 18:58, Neia Neutuladh wrote: From the "it's a hacky workaround but it's what we've got" department: how to use dynamic libraries in dub, with GtkD as the example. GtkD takes about 45MB on its own, and that means it can take a fair bit of time to build anything that depends on it -- even if it only uses a handful of symbols. Building it as a dynamic library can shrink compile times significantly. https://blog.ikeran.org/?p=323 An example of this strategy in use: https://git.ikeran.org/dhasenan/resin-browser/src/master/dub.json And for GtkD, that is why it would make sense to relay on the packages supplied by your distribution. And just list "gtkd-3" in the "libs" section. Avoiding the need for the workaround to build a shared version. -- Mike Wey

class B
{

How would you write an opCast that would handle this case correctly?
Testing if this is null at the start of the opCast doesn't help since
the assert is thrown before that happens.
Making the opCast static leaves us without access to this, which would
be needed in my use case.
We can't relay on ufcs since the rewrite to opCast doesn't happen when
it's not a member function.

Is GstreamerD going to be useful for this or so I look in to using

The Gstreamer demo should use an `playbin` instead of explicitly setting
the pipeline, Like this:

I'd rather not create a value on the heap when I only need it locally.
Could you add a way to create the value with the right type to Value?
Even static constructors would work(probably could templatize it).
Although, I'm not sure how much it matters since value itself seems to
allocate on the heap ;/
public this()

But it might help reduce some memory waste.
`Value` is a class so you will need to use `new`.

public this(Box b)

this.gtkBox = b.getBoxStruct();

Trying something like the above does extend the box, as far as allowing
one to replace it, I think(using the code);
auto b = new MyBox(W1);
auto p = W1.getParent();
auto c = cast(Box)W4;
c.remove(W1);
c.add(b);
So, W4 is the main boxx, W1 is the box inside the main box I replaced
with the new box b.
When running that code, nothing changes, which, assuming we are actually
using the new box, then that is fine.
But I'm pretty sure that gtk never has a clue about `MyBox`? I say this
because I'd like to simply modify the reported sizes of the box.
A gtkBox is not the same as a gtk.Box.
It seems like the best I can do is use a gtk.Container and inherit from
that.
e.g.,
class FixableSizedBox : Container
{
protected GtkContainer* gtkContainer;
import std.typecons;
_gtk.Container Wrapped;
mixin Proxy!Wrapped;
public this(Container b)
{
this.gtkContainer = b.getContainerStruct();
super(gtkContainer, false);
}
}
But even the GtkD container doesn't seem to contain any code to deal
with handling the sizes.
All I'm really looking to do is set the size of a container to whatever
I want.
If you want gtk to know about the functions you override you could use
gtkd.Implement.ImplementCLass.
It's only in master and not completely finished yet, but you could use
it to for example overrride the getPreferredHeight and getPreferredWidth
functions.
I'm not completely clear on what you want to do with the size so they
might not be the correct functions to override.
```
class MyBox : Box
{
import gtkd.Implement;
import gobject.c.functions : g_object_newv;
mixin ImplementClass!GtkBox;
this()
{
//TODO: sort out the constructor.
super(cast(GtkApplication*)g_object_newv(getType(), 0, null), true);
}
override public void getPreferredHeight(out int minimumHeight, out
int naturalHeight)
{
//Set minimumHeight and naturalHeight.
}
override public void getPreferredWidth(out int minimumWidth, out int

//Set minimumWidth and naturalWidth.

Re: Module Info error
On 19-08-17 04:07, Johnson Jones wrote: Still getting this! What I don't understand is why I can import certain libraries and they compile fine while others don't! So, moduleInfo is a "function" per module that is created at compilation, right? If one doesn't compile the module then the error results, just like standard extern functions. When I don't include the file in the project, it doesn't get compiled, even though it gets "imported"? Why? Why can't D just know, hey, module X imports module Y, module Y needs to be compiled to add moduleInfo? For example, I am trying to get ffmpeg to work. I downloaded from https://github.com/complistic-gaff/ffmpeg-d extracted, put that path in my includes(sc.ini). created a module to import the standard modules, tried to compile my project and I get a bunch of ModuleInfo errors relating to the imports I added. I use GtkD exactly the same, yet no errors. Now, the only difference is that I import the gtkD.lib. I'm assuming that all the moduleInfo's of the 1000+ gtk files are in that lib and so That is the reason I don't have the compile them all, is that correct? If so, how can I generate such a lib of moduleInfo's recursively for a directory so I can pick up all the files and just import it once? ffmpeg doesn't require compiling but I don't wanna have to include ever file in to my project just to be able to get it to work because of the moduleInfo's are missing. Looking at the build.d for gtkD, it looks like it builds a list of all the files to compile and does it recursively. I imagine it can be modified for ffmpeg too to create a utility to solve this problem. Dmd should have a mode to do this automatically, it's quite an annoying problem ;/ You need to either compile ffmpeg-d in to a library and include it when you are building your application, or pass all the ffmpeg-d source files to the compiler. It looks like ffmpeg-d only has a dub.json file for building so you will need to use dub to build it eg: `dub build` from the root of the project. -- Mike Wey

A far as i can tell using id's is the only option.
You can use a templated function as a delegate:

You can use the GLCore demo as an example: https://github.com/gtkd-developers/GtkD/blob/master/demos/gl/core/CoreGL.d GtkDGL wraps gtkglext3 which is currently not maintained, and no longer has any binaries available. -- Mike Wey

Would be nice if the error message printed the full path of what was being loaded so it's quicker to diagnose. Seems there is a > ... code ... which is used, could I just hijack this to set the correct path based on what version it is compiled under? Would be the easiest thing, at least as a temporary workaround. You renamed the gtk DLL's, i assume you simply renamed them, but to get things working with different names you would need to build GTK from source, and apply the appropriate patches to GTK and its make files. If you would use a dependency walker on libgtk-3-0.dll you can see that it depends on basically all the other dll's in the directory, and by renaming them they can no longer be found. For libraries that are in both GTK 3 and GTK 2 it might find the libraries distributed with gtksharp but that would also fail because of the version difference. Printing the full path of the library in the error would only only be possible if we call LoadLibrary with the full path. It's been a while since i implemented the architecture check but if i remember correctly there were some issues with that. Otherwise it might be loaded from one of the other directories LoadLibrary searches, and then the printed path would be wrong, making things even worse. And yes you could hard code the path that is passed to SetDllDirectory as a work around, but the dll's will need to have there proper names. -- Mike Wey

Do you guys actually test out both versions installed on the same system? Gtk also loads some of it's own libraries at start up with GModule / LoadLibrary. So with the library names changed GTK might be loading the Gtk 2 libraries installed with gtksharp instead of the correct ones. -- Mike Wey

Re: gtk arch issues
On 31-07-17 19:16, Johnson Jones wrote: how does one allow both gtk x86 and x64 to work side by side seamlessly? I installed x64 first and it seems, because whatever is using the path to find the gtk runtime, it looks for that first even in x86 build. Seems like gtkd's dll resolution is not very intelligent. While I could manually modify the path each time I switch archs, that seems pointless. One of the problems in gtkd is that it has multiple places where it defines libgdk-3-0.dll. I've tried modifying gdkD so that it uses versioning properly by searching for libgdk-3-0.dll and changing all to use an x86 or x64 when appropriate but that doesn't seem to help. Probably have to rebuild gtkD. Anyways, doesn't seem to be a great solution ;/ Any ideas and maybe someone can add an issue to the github page to get this fixed? (I can't do it for a while because of other issues). At startup GtkD searches the Path for "libgtk-3-0.dll", when it finds one it checks the architecture of the library. If it's the correct architecture it calls `SetDllDirectory` so that the directory with the correct architecture will be searched first by `LoadLibrary`. If it's not the correct architecture it continues searching, if no library with the correct architecture is found, we rely on `LoadLibrary` to error out if the libraries are also not in the other locations searched by `LoadLibrary`. -- Mike Wey

What is this file? simply doing dmd -m64 build.d Works fine for x86. I was able to get this to work by copying all the required lib's to the lib dir from the windows sdk(liburct.lib, shell32.lib) and copying link.exe to x64. The program compiles, but when ran, I get the error object.Exception@generated\gtkd\gtkd\Loader.d(125): Library load failed (libgdk-3-0.dll): is not a valid Win32 application. which I assume is due to the fact that I have x86 gtk installed(I think, as I thought I installed the dual package... can't seem to find x64 gtk3+ standalone). Yes, that error is probably because you only have the 32bit version of the GTK runtime installed. On gtkd.org installers for both 32bit and 64bit are available, they can be installed side by side without any issues. -- Mike Wey

Can any of the current D solutions work such as GtkD or QtD? I'm looking for something somewhat lightweight, easy to use(I find GtkD a bit funky but it does seem to work and is relatively easy once one gets through the basics). I think having a GUI builder is crucial though as it makes it so much easier in the long run. Glade is a bit funky but functional and works. Ideally I'd like to be able to make portable apps that just work across the board(mac, linux, windows, android) without much hassle. Mike said maybe later, when I asked him in January: http://forum.dlang.org/post/o4rq0i$dur$1...@digitalmars.com In the meantime, you can try DlangUI, as Seb pointed out, but I get the impression it's not touch-optimized, just like Gtk. And if you want something lightweight, the complete GTK stack is probably not what you are looking for. -- Mike Wey

What does "case [c]:" mean?
In the static foreach c is a `immutable char` by putting it between [
