IJ.doCommand(???) and ThresholdAdjuster

[Carl Trapani - SkyTop Software]

Hi Everyone,

Does anyone know what the commands are that can be passed to
IJ.doCommand(String command)? Are there constants defined somewhere or
some type of naming scheme?

I'm trying to run the ThresholdAdjuster from my class when the user
clicks a button. My class extends PlugInFrame. My idea is to just use
IJ.doCommand("Threshold"), but that isn't working. I've also tried
IJ.runPlugIn("ThresholdAdjuster", null), but that doesn't appear to do
anything?

Thanks in advance for any tips.

Hi,

Have you try with the empty string,
IJ.runPlugIn("ThresholdAdjuster", "")

It work with my plugin.

IJ.run() and IJ.doCommand() can be passed any ImageJ menu command. Use
the Plugins>Utilities>List Commands (or Find Commands in v1.41) command
to get a list of all the menu commands. You can also get a command name
by running the command with the recorder running. Both IJ.run() and
IJ.doCommand() run the specified command but IJ.run() does not return
until the command finishes whereas IJ.doCommand() runs the command in a
separate thread and returns immediately. You can use use either
IJ.run("Threshold...") or IJ.doCommand("Threshold...") to open the
Threshold window.

Excellent! Thanks Wayne. Thanks also for an amazing tool!

For anyone else out there, here is a code snippet that may be useful (or
may not). It appears that the buttons for ThresholdAdjuster are inside a
panel:

ThresholdAdjuster ta =
(ThresholdAdjuster)IJ.runPlugIn(ThresholdAdjuster.class.getName(), null);
//Now I have a reference to ThresholdAdjuster
Component[] comps = ta.getComponents();
IJ.write("There are " + comps.length + " components in ThresholdAdjuster.");
for (Component c : comps) {
    IJ.write("Component " + c.getName());
    if (c instanceof Button) {
        Button b = (Button) c;
        b.setVisible(false);
        IJ.write("Found Button " + b.getLabel() + " and
setVisible(false).");
    }
    else if (c instanceof JButton) {
        JButton b = (JButton) c;
        b.setVisible(false);
        IJ.write("Found Button " + b.getText() + " and setVisible(false).");
    }


Output:
There are 7 components in ThresholdAdjuster.
Component canvas0
Component scrollbar0
Component label0
Component scrollbar1
Component label1
Component choice0
Component panel0
