How could I open more than one image with a single dialog in Digital Micrograph script? - dm-script

Question

I am writing in DigialMicrograph scripting. I want a script to open more than one image in a single dialog, a multi-select image dialog, similar to when you go to any Windows open dialog, select several images and press Ok.
I think that this is possible but I haven't found a way to do it. I want to introduce this specific code in my script, to avoid image-opening prior to running the script.
I know the function OpenDialog but this only allows opening of a single image. Could anybody show me some script or a function which can help me further?
Thanks.

What you are asking for might be a bit more involved. There is no multiple open function in the scripting language, so you can only create it yourself, involving multiple steps:
An input for a base-folder (This you could prompt the user for with a GetDirectoryDialog dialog)
Using the command GetFilesInDirectory to retrieve a list (TagList) of files in that folder
Process that list to filter out what you are interested in
Build a custom-dialog (derived from UIFrame) which lists the files with either checkboxes, multiple drop-down menus, or a list-box to select from.
Act on the selection made in your custom dialog, i.e. open all those files
The following script is an example doing that.
class MyMultiSelect : UIframe
{
string root
TagGroup FileList
TagGroup DLGlist
TagGroup CreateDLG( object self )
{
TagGroup dlg,dlgitems
dlg = DLGCreateDialog( "MultiOpen", dlgItems )
number nMax = fileList.TagGroupCountTags();
TagGroup listitems
DLGlist = DLGCreateList( listitems, 90, nMax+1 )
DLGlist.DLGMultipleSelect(1)
for (number i=0; i<nMax; i++)
{
string name
if ( FileList.TagGroupGetIndexedTagAsString(i,name) )
listitems.DLGAddListItem( name, 0 )
}
dlgitems.DLGAddElement(DLGlist)
return dlg
}
TagGroup CreateFilteredFileList( object self )
{
// Get all files
TagGroup list = GetFilesInDirectory( root, 1 )
// Filter all DM3 files
TagGroup filtered = NewTagList()
for( number i = 0; i<list.TagGroupCountTags(); i++)
{
TagGroup entry
string file = ""
list.TagGroupGetIndexedTagAsTagGroup(i,entry)
entry.TagGroupGetTagAsString( "Name", file )
if ( -1 != find(file,".dm3") )
filtered.TagGroupInsertTagAsString(Infinity(),file)
}
return filtered
}
TagGroup GetSelectedList( object self )
{
TagGroup selList = NewTagList()
TagGroup itemList
DLGlist.TagGroupGetTagAsTagGroup( "Items", itemList )
for ( number i=0; i<itemList.TagGroupCountTags(); i++ )
{
number isSelected = 0
TagGroup entry
itemList.TagGroupGetIndexedTagAsTagGroup(i,entry)
entry.TagGroupGetTagAsBoolean( "Selected", isSelected )
if ( isSelected )
{
string filename
entry.TagGroupGetTagAsString( "Label", fileName )
selList.TagGroupInsertTagAsString( Infinity(),fileName)
}
}
return selList
}
void OpenSelectedFiles( object self )
{
TagGroup files = self.GetSelectedList()
number nFiles = files.TagGroupCountTags()
if ( 0 == nFiles )
Throw( "No files selected" )
Result( "\n Opening "+nFiles+" files now..")
for ( number i=0; i<nFiles; i++ )
{
string filename
files.TagGroupGetIndexedTagAsString(i,fileName)
string path = root + "\\" + filename
Result( "\n Opening: "+path)
OpenImage(path).ShowImage()
}
}
Object Init( object self, string rootInput )
{
root = rootInput
FileList = self.CreateFilteredFileList( )
return self.super.Init( self.CreateDLG() )
}
}
// Main
{
string rootDir
GetDirectoryDialog( NULL, "Select Folder from which to multi-open", GetApplicationDirectory("current",0), rootDir )
object dlg = Alloc(MyMultiSelect).Init(rootDir)
dlg.pose()
dlg.OpenSelectedFiles()
}
