#51 How tu use image in container ?

[Aupeix Alain]

Hi,

I have tried to use bincnt, and it seems nice to gropu icons and images in one file.

But how to keep these images or icons in an hwgui program ?

Thanks

Sorry for the noise, I have found the answer in HwGui documantation ...

Hum, trying that :
~~~hwg_SetResContainer( cpPath + "/hwmake.bin" )
oBitmap := HBitmap():AddResource( "open" )
@ htab+(nbut*32), 3 OWNERBUTTON OF oToolbar ;
ON CLICK {||Container()} ;
SIZE 28,24 FLAT ;
BITMAP "container" FROM RESOURCE TRANSPARENT COLOR ;
hwg_ColorC2N("#DCDAD5") COORDINATES 0,4,0,0 ;
TOOLTIP _("Gérer un container")~~~

No error, but image isn't displayed

Content oy hwmake.bin:

container png
hwmake  png

Where do I fail ?

Hello Alain,
see HWGUI Docu:

doc/hwgdoc_commands.html

4.3.27. @ <x>,<y> BITMAP
...
Supported image formats: bmp, jpg </y></x>

For png it is necessary, to use the IMAGE term, but you must link the
FreeImage library to your application.

Please try the following:
- Convert your png's to *.bmp
For example with Windows utility "Paint".
- Replace the ressources with the Binary container manager.
- Start your app again.

I hope, this helps you.

Otherwise i need a sample to retrace your problem.

Thanks, I saw it;
I add -lhbmagic, but it doesn't work

cImageDir := cppath+"/image/"
// Ouverture du container
hwg_SetResContainer( cImageDir + "hwmake.bin" )

//oIcon := HIcon():AddFile( cImageDir+"geneweb.png" )
oIcon := HIcon():AddResource( "geneweb" )
...
oBitmap := HBitmap():AddResource("open")
@ htab+(nbut*32), 3 OWNERBUTTON oFileOpen OF oToolbar ;
   ON CLICK {||FileOpen()} ;
   SIZE 28,24 FLAT ;
   BITMAP oBitmap TRANSPARENT COLOR hwg_ColorC2N("#DCDAD5") COORDINATES 0,4,0,0 ;
   TOOLTIP "Ouvrir un fichier"
nbut+=1

@ htab+(nbut*32),3 OWNERBUTTON oReadReg OF oToolbar ;
   ON CLICK {||ReadReg()} ;
   SIZE 28,24 FLAT ;
   BITMAP cImageDir+"lire.png" TRANSPARENT COLOR hwg_ColorC2N("#DCDAD5") COORDINATES 0,4,0,0 ;
   TOOLTIP "Lire un registre"
nbut+=1

As you can see with the two screen:
Before using the container, it works for icon and buttons using png image
Using the container, it doesn't work anymore.
It seems that BITMAP parameters wants a filename, and container gives the content of the file ...
When using BITMAT from RESOURCE, RESOURCE gives the fileanme (and path) of the image, and that's why it works

Am-I wrong ?

Hello Alain,
I needed some time to create a full sample to
retrace the case (r2869).
The new sample works best with WinAPI,
but the PNG is not visible/supported in the OWNWERBUTTON
(i documentated this a few days ago).

There is really a bug in the GTK implementation,
please be patient, i need some time for analysis.

If you have some ideas in the meantime, please post them.
To be continued !

Hi Wilfried,
I have replaced the png file by a jpg file, and it doesn't work too.
So it seems evident that the problem isn't due to png, but the use of a container.

As I suppose the the command

oBitmap := HBitmap():AddResource("open")

returns athe contant of the file, the parameter is now a binary, not a path, so I suppose that ownerbutton is waiting for a path, not a binary ...

If so, it could perhaps be possible to test the content of the param to see if it's a binary, and perhaps its type in ownerbutton source ?

For Windows test, have you test with bincnt or rc ?
If you have use bincnt, the only location where it fails is ownerbutton or gtk ...

Thanks
A+

[Aupeix Alain]

other test:

// Ouverture du container
test=hwg_SetResContainer( cImageDir + "hwmake.bin" )
qout("*************")
qout( cImageDir + "hwmake.bin" )
qout(test)
qout("*************")
oBitmap := HBitmap():AddResource("open")
//oBitmap := hwg_BmpFromRes("open")
qout(oBitmap)

returns :

*************
/opt/GeneTools/image/hwmake.bin
.F.
*************
NIL

Tests made with with AddResource and BmpFromRes ... and a jpg image

It seems that SetResContainer is the reason of the problem ...

Hello Alain,
MNI TNX for your last posts.
I give you an intermediate status report:
The problem is, that the binary container
stores and reads the contents with MEMOWRITE and
MEMOREAD.
For displaying an image GTK has it's own format
"GDK pixbuffer", there seems to be a conflict.

I have some ideas to solve this and must read a
lot of instructions in the GTK reference.

Please be patient, i hope that i can deliver a
fix in the next few days.

Hello Alain,
after a full sunday's work i fixed
the problem.

The first problem was solved in
source/gtk/drawwidg.prg:
::handle := hwg_Openimage( cVal ) && 2nd parameter not .T. !
First trying to read from file,
in case cVal is PIXBUFF data, the above call fails and the
cVal was now interpreted as contents
of an image. It is written into
a temporary file and now the image
was loaded succesfully from file
with function hwg_Openimage().

hwg_Openimage( name , ltype )
ltype : .F. : from image file
.T. : from GDK pixbuffer
returns handle to pixbuffer

The second problem is the
TOOLBOX command.
Substituted by the PANEL command,
(Oh what a wonder !) the
ownerbuttons are now visible !
(I think, that is OK for you)
I found this sample in the tutorial.

With call of function
hwg_CreateTempfileName()
the creation of names for
temporary files is multi platform ready.
So the sample also works on WinAPI and
the GTK cross development environment on Windows 10.

On LINUX, the formats .bmp, .jpg and .png are supported.
on Windows GTK only .bmp.

I appended a snapshot from my LinuxMINT system,
the icon appears here in the task bar.
and is also visible (ok.ico).

If you do not want to get the complete code snapshot,
change or add files from the commits
r2872 and r2871.

Use the sample program
/trunk/hwgui/samples/gtk_samples/bincnts.prg
for check.

Please give feedback, if Alexander Kresin can close the ticket.
Thank you for your support. It is a good idea for me,
to invent the binary container in my application "CLLOG".

Hi Wilfried,
Thanks for your efforts, but it doesn't solves my problem

Here are the lines about this problem:

hwg_SetResContainer( cpPath + "/hwmake.bin" )
...
oBitmap := HBitmap():AddResource( "container" )
   @ htab+(nbut*32), 3 OWNERBUTTON OF oToolbar ;
      ON CLICK {||Container()} ;
      SIZE 28,24 FLAT ;
      BITMAP oBitmap TRANSPARENT COLOR hwg_ColorC2N("#DCDAD5") COORDINATES 0,4,0,0 ;
      TOOLTIP _("Gérer un container")

Do I made some error ?

Thanks

[Aupeix Alain]

Hi,
Your sample works, so I tried to see what was the difference

Here are two screenshots which can perhaps explain why ...
Concerning theresolution, I don't think it's the problem, but hexdump shows differences sBIT (my png) and sRGB (yours)
I put my png to let you try on your system ...

Thanks

Hello Alain,
i have done the following steps to retrace your problem
(LinuxMINT Cinnamon):
I added "container.png" with the Manager on this LINUX system
and this image is also visible.
The container with the first images was created on Windows.
Result see commit r2874.
Appended my screenshot.
The image is OK.
Tomorow i can check it against Ubuntu 16.

I am pleased looking to the screenshot of your utility.
I think, it could be useful for other LINUX friends using Harbour + HWGUI.
Do you decide to release it as Open Source ?

Hi!
Here works. But file astro.png with bug.
Open file and add hwgui.png with sucess! Via /utils/bincnt

Hi Itmar,
What is the linux build and the version you use ?
For me with Xubuntu 16.04, it fails ...

Wilfried,
concerning hwmake linux, I have some little problems to solve, a feature to do, and I have to make the doc ...
Features are :
Manage hwmake
. Manage harbour and hwgui folders
. Manage harbour, contrib and hwgui libraries
. Set needed tools to use hwmake functionalities
. Manage (Create, update, set) languages files for hwmake (po and hbl files), for now, french and english.
. Acces to the source of hwmake, to the hwmake todo file
. Acces to harbour, hwgui, clipper documentations (local and online)
Manage the projects (open, create and save)
Manage the debugger
Manage the warnings
Build the projects
Run the project
View log files
Open the terminal or filebrowser in the source folder (of the project)
* [ToDo] Manage (Create, update, set) languages files for projects (po and hbl files)

It has been made starting from the Windows version. For a few thing I have created functions to works like windows functions work (inifile functions, ...)
I sent it to Alexander, but he seems notinterested to add it to utils. I suppose he was too busy, and i find, this tool a little old and not too much interesting ...
For now, I have the original version in my own folders, but I have also locate in in hwgui source folder (utils/hwmake/linux/hwmake)

When it will more achieved, I'll send it ... and obviously it will be under the same license than hwgui.

Thanks

Hello Itamar,
the image astro.png is ok on my system an in svn repo. It has 24915 Bytes.
I added this to the binary container and modified the sample
for display it with the BITMAP command.
The result is in the appended screenshot.
Committed with r2875.

Hello Alain,
TNX fer offer to publish the hwmake-linux as Open Source.

If the app is achived, there are 3 alternatives:

1.) Ask Alexander for giving permission as a developer of HWGUI.

2.) Post the first issue via the ticket #51 and i will test and commit it.

3.) The best case: You have an account on sourceforge.net and
so you can create an own project and you are the project admininstrator.
First it is necessary to create the basic directories trunk, branches
and tags.
For support you can give me permission to checkin into Subversion repository,
if you want.

I use the svn command to manage the source code.

If your choice is 3, i will add a link in the HWGUI documents.
