Event that captures mouse action

[Langen, Gido]

Some javascript/style in this post has been disabled (why?)

Does anyone know how to capture a mouse click on the map?  I want to do some scale dependent processing and want to capture the scale after zooming in/out.  I need to know the scale right after the zoom in/out, before the map is redrawn. 

Thanks for any insight,
Gido

There is a function called "OnMapLoading" which you can hijack like this:

//Keep a reference to the original function
GetMapFrame().original_OnMapLoading = GetMapFrame().OnMapLoading;

//Assign a new function
GetMapFrame().OnMapLoading = function(){

    try {
       
       //Place more meaningfull code here :)
        alert("The map is now loading");

    } catch (e)  //Make sure our code does not break the function
    {}

    //Activate the actual MapGuide handler
    original_OnMapLoading();
};

Hi Kenneth,

 

Thanks so much for your example.  It worked really well.  I have listed my working copy as further reference. 

Now, I have one more question: I want to associate the functionality with a new command on the toolbar which is easy enough.  The trouble is that the new command can be activated by clicking it but it does not STAY selected like the built-in commands once they have been activated.  So, how can I make a custom command stay selected after it has been activated?

 

Thanks,

Gido

 

 

// Copy original function to new pointer
origOnMapLoadingFunc = parent.parent.mapFrame.OnMapLoading;

 

// Redefine old OnMapLoading function
parent.parent.mapFrame.OnMapLoading = function() {
  // Does somethimg
}

 

// Call "new" functionality
paren.parent.mapFrame.OnMapLoading();

 

//Run old function
origOnMapLoadingFunc();
