File and Node Pickers

RealFlow’s interface provides several tools for opening files from your local or network hard disks, and also allows you to select various nodes from a list. These tools can also be used for your own GUI windows. You have full access to these pickers and they offer full functionality, like filtering certain file or node types. There is a fixed code structure for opening the file picker dialogue: 

files = GUIFilePickerDialog.new()
path = files.show(FILE_PICKER_LOAD, "PATH", "*.tif;*.tga", "Load Maps")

The files.show() statement contains a series of arguments. The first statement, FILE_PICKER_LOAD, opens the file loader. If you want to save files, replace it with FILE_PICKER_SAVE. The next part specifies the path of directory that will be opened. This path has to be adjusted to your own needs, of course. With the next argument it is possible to restrict the file list to a certain type. In this case only TIFFs and TGAs are displayed. If you want to show all files, use the  *.* notation. Finally you can apply a name to your window. It is just entered between quotation marks, like any other string.

The calling of a node picker is pretty similar to the file picker. First, the window has to be initialized and then you can specify the desired options to filter the available nodes:

dialog = GUINodesPickerDialog.new()
nodes = dialog.show( TYPE_EMITTER | TYPE_DAEMON )

for single_node in nodes:
    scene.message(single_node.getName())

With TYPE_NODE it is possible to restrict the displayed nodes to a certain type:

TYPE_CAMERA

TYPE_DAEMON

TYPE_OBJECT      

TYPE_PB_EMITTER

TYPE_EMITTER

TYPE_STANDARD_MESH (or: TYPE_MESH)

TYPE_MESH 

TYPE_JOINT

TYPE_GROUP 

TYPE_REALWAVE 

TYPE_MIST 

TYPE_IDOC 

TYPE_GRID_MESH 

TYPE_GRID_DOMAIN 

TYPE_RENDERKIT_MESH 

TYPE_GB_EMITTER

TYPE_MULTIBODY  

ALL_TYPES 

The individual types are separated with a pipe character, which can be added by pressing AltGr + > (Windows/Linux) and Alt + 7 (OS X).
