When you use the viewer api (DigitizeRectangle...) with IExplorer 7/8, on mouseUp you're callback function is thrown but the "mouse" is not well released.
I explain: the digitizer work, call the callback function, but the mouse seems to be "traped" in the mapspace:
when i move the mouse pointer in the legend frame (or other frame if my viewer is in a frameset) i can see the x/y mouse position of the status bar been updated.
If i move the pointer over an hyperlink or simply a mapguide toolbar button, the hover event is not fired.
after one click everything work well again.
On webApplication where i used a custom overviewmap (my overviewmap use the DigitizeRectangle), the behavior is worst..
i found a trick that could help: after hours on this problem i found that the bug is in wz_jsgraphic in the clear function. when the shape div has it innerHtml reseted..
as solution i replaced these digitizer function:
this.InitFeedback = function()
{
var rd = document.getElementById(this.fbDiv).style;
rd.position = "absolute";
rd.left = this.fbPos + "px";
rd.top = "0px";
rd.width = this.fbW + "px";
rd.height = this.fbW + "px";
rd.visibility = "visible";
rd.clip = "rect(0px " + this.fbW + "px " + this.fbH + "px " + "0px)";
}
this.ClearFeedback = function()
{
if(this.fbDiv)
document.getElementById(this.fbDiv).style.visibility = "hidden";
if(this.fbShape)
this.fbShape.clear();
}
by
this.InitFeedback = function()
{
if(this.fbShape)
this.fbShape.clear();
var rd = document.getElementById(this.fbDiv).style;
rd.position = "absolute";
rd.left = this.fbPos + "px";
rd.top = "0px";
rd.width = this.fbW + "px";
rd.height = this.fbW + "px";
rd.visibility = "visible";
rd.clip = "rect(0px " + this.fbW + "px " + this.fbH + "px " + "0px)";
}
this.ClearFeedback = function()
{
if(this.fbDiv)
document.getElementById(this.fbDiv).style.visibility = "hidden";
}
The div innerhtml is cleared when the digitizer start instead of digitizer end.
It works for me.
Good luck with digitize!
