The select a signal dialog is not currently accessible to modders and I'm hoping to get that changed

The element itself would operate similar to either the sprite-button, or more preferably the button used in the combinator windows.

On clicking it, the modal dialog would appear and the gui_on_click event would be generated when the window closes.

When the window closes, the selected signal would be updated to a variable stored in the GUIelement class. If no signal was selected, the variable is not updated.

It would be better if there is GUI type "virtual-signal-slot", which will show a slot button. Users can select virtual signal after clicking the button, just like selecting signal for the combinators. This way, we modders don't need to deal with the signal selection window. But a new event may be needed for getting the selected signal, maybe on_gui_virtual_signal_selected.

Similarly, another GUI type "item-filter-slot" can also be implemented like this.

If you are looking for customized signal selection window, you can always do that by iterating game.virtual_signal_prototypes and drawing sprite button for each signal.

I imagine the data would be stored via a new variable in the GUIelement class, and raise the on_gui_clicked event after the select a signal window was closed.

I'm looking at making the window myself, but unfortunately I need to iterate items and fluids as well as virtual signals.

making the item-filter-slot accessiable in a similar fashion would also be nice.

What I might be able to do is give access to the "choose-X" widgets we have.

Specifically we have the following dedicated widget types we use:

• ChooseEntityButton
• ChooseItemButton
• ChooseSignalButton

Where each of them allows selecting one of the associated types through the normal pop-over GUI. They're used for signals, filters, and such.

that would work perfectly.

That would be one of the best additions to .15!

We really need a FFF about all the changes on the GUI system once they are implemented. #cantwaitfortheupdate

This would allow me to work around different issue.

is there any update on the status of this?

Apparently the feature is implemented.
