Re: [OpenMap Users] popupmenus for my iamges?????????

Hello Harpreet,

If your layer is receiving and processing mouse events then you can do
something like this:-

    /**
**************************************************************************
     * The popup menu for the right click on the plot point
     */
    private JPopupMenu popup = null;
    .
    .
    .

In the constructor ...

    // Build the popup menu for this layer //
    popup = new JPopupMenu(); //
Create the layer popup
    JMenuItem deleteItem = new JMenuItem("Delete Symbol"); //
Create a Delete menu item
    deleteItem.addActionListener(new ActionListener() { //
Create its action listener
        public void actionPerformed(ActionEvent evt) { //
            deleteItemAction(evt); //
Execute the method
            } //
           }); //
        popup.add(deleteItem); //
Add item to popup menu
    .
    .
    .
    public boolean mouseClicked(MouseEvent e) { /////////////////////////
mouseClicked()
                                                                       //
        if ((e.getSource() instanceof MapBean) == false) //
If not from a MapBean
            return true; //
Then return
                                                                       //
        Context.debug(getClick(e)); //
Debug mouseClicked
                                                                       //
        characteriseClick(e); //
Figure out the click type
                                                                       //
        // If there is any marqueed symbol then remove the marquee. //
        if (marqueed >= 0) { //
If have marqueed one
            drawMarquee(marqueed, e.getX(), e.getY()); //
Remove marquee
            marqueed = -1; //
Flag none marqueed
            } //
        if (vanillaClick && rightClick && (gList.size() > 0)) { //
If popup and have symbols
            thisIcon = null; thisText = null; //
Nothing selected
            thisIndex = findNearest(e.getX(), e.getY(), clickRange); //
Find nearest symbol
            if (thisIndex != OMGraphicList.NONE) { //
If found one
                netINFO.setStatus("Selected symbol " + thisIndex); //
Update status
                thisIcon = (OMRaster)gList.getOMGraphicAt(thisIndex); //
Get icon reference
                thisText = (OMText)tList.getOMGraphicAt(thisIndex); // Get
caption reference
                popup.show(e.getComponent(), e.getX(), e.getY()); // Bring
up popup
                } //
            } //

So this bit of code in the mouse event handler just looks for a right
click to activate the popup menu. From there it's down to the menu item
action event handler to implement whatever you want to do.

You can plot anything you like. You just need to relate the click point to
whatever is one the map in some way. In the code above I look for an item
in an OMGraphicList that is within range of the click. In this case I have
two lists, one holding images and one holding text labels.

Hope that helps,

with best regards,

Adrian

hi there

i am making a layer that will plot some images(ImageIcon) on the openmap
on the basis of lat/lon using OMGraphics and when a right click is made on
the image a popup menu shoild appear....

i know this can also be done with the CSVLocationHandler class and the
Gestures mode, but......,the problem part is that in the gestures mode
there are 2 types of popupmenus one is set city locs and other on the
panel area

now wut i want to know from u is that in my class how can i set the popup
for the images(ImageIcon), as there is no such event for images

pls tell me wut approach should i follow
guide me if there are any such API's in ur application
or should i plot something other than a iamge

pls guide me in some simple steps
if any of you have done anything in related to this then pls give some
tips

thanxxx
Harpreet
