File chooser

Hi,
I want to select multiple files with the file_choose.
I did it like this:

CPP / C++ / C Code:
use_system_file_chooser(true);
.
.
.
file_chooser("Select files", "all files (*.*)\0*.*\0\0", NULL, false);

It works for selecting one file, but how to select more ???
I'm using FLTK2 under Win2K...

I tried it also like this:

CPP / C++ / C Code:
FileChooser fc("dir", "*.*", 0, "titel");
fc.type(1);
fc.exec();

this way I can select multiple files, but don't get them when clicking on "OK" !!!
And it's not the window's file chooser but the FLTK's file chooser (I want the window's chooser)...

How can I select more than one file ???

thx, Acki

Re: file chooser

I'm sure Acki has moved on in the last 9 months; but for other peoples benefit the file_chooser function returns a pointer to the filename selected, or NULL: http://www.fltk.org/doc-1.1/function..._file_chooser2

The file_chooser class however is more flexible: http://www.fltk.org/doc-1.1/Fl_File_...l_File_Chooser

This is the constructor:
CPP / C++ / C Code:
Fl_File_Chooser(const char *pathname, const char *pattern, int type, const char *title)

Here's an example to select multiple files (I think I adapted this from one of erco's examples: http://seriss.com/people/erco/fltk/):

CPP / C++ / C Code:
Fl_File_Chooser chooser( ".", "Image Files (*.{gif,jpg,jpeg,bmp,png,tif})", Fl_File_Chooser::MULTI, "Please select image" );                 
chooser.show();

// block until user picks something.
while( chooser.shown() ) { Fl::wait(); }

// display filenames selected - index starts from 1
for( unsigned int i=1; i <= chooser.count(); i++ )
    cerr << chooser.value(i) << endl;

Re: file chooser

Thanks for the Fl_File_Chooser example! I was just trying to use it and couldn't figure out how to get the filename as easily as you showed. Didn't know about shown().

Re: file chooser

hello!
i tried to add file_chooser in code, but at linking step i obtain an error:
Quote:
[Linker error] undefined reference to `AlphaBlend@44'
AlphaBlend is from wingdi library. First quetion - where file_chooser may use wingdi???
adding -lgdi32 option for linker do not solve this problem. How i can eliminate this error?
thanx

Re: file chooser

My guess is you need to link to the fltk images lib. If you are using fltk-config add --use-images and all will be well.

If you search this forum you for --use-images you should find the way to link it otherwise. When in doubt, I just run from the command line,

Code:
fltk-config --ldflags --use-images

Here is a sample,
Code:
$ fltk-config --ldflags
-L/usr/local/lib -mwindows -lfltk -lpthread -lole32 -luuid -lcomctl32 -lwsock32

$ fltk-config --ldflags --use-images
-L/usr/local/lib -mwindows -lfltk_images -lfltk_png -lfltk_z -lfltk_jpeg -lfltk -lpthread -lole32 -luuid -lcomctl32 -lwsock32

Re: file chooser

i dont use fltk-config. I compile with Dev-Cpp. And i want to use fltk2, not fltk 1.1.x
adding --use-images key do not solve this problem

Re: file chooser

Hey,
I'm using FLTK2 on Win32 (XP) and would like to have the native System File Chooser instead of the FLTK file chooser. I tried the following:
CPP / C++ / C Code:
fltk::use_system_file_chooser(true);
fltk::file_chooser("Open file", NULL, NULL);
But when I compile my application an error occurs:

CPP / C++ / C Code:
error LNK2019: unresolved external symbol "__declspec(dllimport) void __cdecl fltk::use_system_file_chooser(bool)"
Did I forget an include library or did I disregard anything else?
Any advices appreciated!
