i have custom treeview-like control in panel in application. click on items receive keyboard focus. it's possible select set of items in tree , cut or remove them pressing ctrl-x or delete. when tree items removed, keyboard focus reverts main window. this leads trouble - if undo cut, elements keyboard focus no longer on panel can't (for example) go cut-undo-cut-undo-cut. what determines keyboard focus moves when element removed? tried making panel have isfocusscope="true" didn't seem have effect, , focus overview doesn't mention how control focus goes when element removed. i guess best bet might setting focus manually after undo/redo (maybe encapsulating in behavior listens events focusmanager sends?) see set focus on textbox in wpf

this question has answer here: segmentation fault on large array sizes 5 answers if keep value of rows 100000, program works fine, if make rows 1 million 1000000, program gives me segmentation fault. reason? running below on linux 2.6x rhel kernel. #include<stdio.h> #define rows 1000000 #define cols 4 int main(int args, char ** argv) { int matrix[rows][cols]; for(int col=0;col<cols;col++) for(int row=0;row < rows; row++) matrix[row][col] = row*col; return 0; } the matrix local variable inside main function. "allocated" on machine call stack. this stack has limits. you should make matrix global or static variable or make pointer , heap-allocate (with e.g. calloc or malloc ) memory zone. don't forget calloc or malloc may fail (by returning null). a better reason heap-allocate such thing dimensions of mat...

i have drawn circle using l.circle weight 1px. want change weight 2px on hover smooth animation. as changing "weight" of l.circle (which in fact svg shape "stroke-width") on hover, bind callbacks on "mouseover" , "mouseout" events: mycircle.on({ "mouseover": function () { mycircle.setstyle({ weight: 2 }) }, "mouseout": function () { mycircle.setstyle({ weight: 1 }) } }); as smooth animation, have 2 options: css3 transition on svg properties. ie not support them unfortunately. fallback implementing animation / transition yourself, typically using setinterval or requestanimationframe , , adjusting weight gradually. with css3 transition on svg properties: javascript: var mycircle = l.circle(mylatlng, myradius, { weight: 1, classname: "test" }) css: .test { transition: stroke-width 1s; /* duration unit */ } demo: http://jsfiddle.net/ve2huzxw/1...
