Rotate WPF control or change screen orientation -

-

i have wpf project 1 window (mainwindow). depending upon config file shows 1 of 2 usercontrol's content. may horizontal (1920x1080) control or vertical (1080x1920) control. it's fine horizontal screen, when vertical loaded do:

1) rotate window/control 270 degrees 2) change primary screen orientation

i prefer rotate application , don't interact windows api. can't change orientation manually, because have remote access computer.

you can not rotate window object itself, positioned window management system built in windows. can, however, transform (and rotate) frameworkelement inside window. includes, not limited to, grid, button , textbox elements.

all need edit layouttransform property on element want rotate, root element in window. set rotation 270/-90 degrees , wpf automatically rotate ui.

because using layouttransform property, layout system scale ui correctly. rendertransform property causes control first rendered, rotated.

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
