BigDataViewer: Help Window

Tags: #<Tag:0x00007fd69bb99d48> #<Tag:0x00007fd69bb99500>



I noticed, while going through the BDV tutorials, that the F1 shortcut producing the help window stopps working once BdvHandlePanel is used on a Jframe. So for tutorial 1 the help window pops up and starting from tutorial 2 there is no response upon pressing F1.

Feature or bug?
Anyway, is there a possibility to keep the help functionality working while working with BdvHandlePanel? Do I have to re-register the F1 keystroke?



The help window seems not to working per default when using bigdataviewer-vistools i.e. BdvHandlePanel.
On startup of the BDV the message “Press for help.” is still displayed though.

Personally, I (re-) registerd the help dialog as follows:

JFrame window = new JFrame("BDV");
BdvHandlePanel bdvHandle = new BdvHandlePanel(window, Bdv.options());
window.add(bdvHandle.getViewerPanel(), BorderLayout.CENTER);

// Add the help window
final InputMap inputMap = new InputMap();
InputTriggerConfig triggerConfig = BigDataViewer.getInputTriggerConfig(ViewerOptions.options());
KeyStrokeAdder adder = triggerConfig.keyStrokeAdder(inputMap);
adder.put("help", "F1", "H");
final ActionMap actionMap = new ActionMap();
new ToggleDialogAction("help", new HelpDialog(window, BigDataViewer.class.getResource("/viewer/Help.html"))).put(actionMap);
bdvHandle.getKeybindings().addInputMap("bdv", inputMap);
bdvHandle.getKeybindings().addActionMap("bdv", actionMap);

Edit: the help dialog requires to be attached to a window, which explains why it’s not working when usnig the BdvHandlePanel.


You might want to mention @tpietzsch and @axtimwalde directly, as I’m not sure if they subscribed to the bigdataviewer tag on this forum (subscription can be triggered per tag at the top right on the tag page).
