c++ - Can I run code *after* a built-in wxWidgets event is handled? -

-

i suspect there must built-in way this, google-fu has failed me.

i'm using wxscrolledwindow, , have paint unscrolled background picture behind contents each time window scrolled. i've made scroll handler this...

void homewindow_t::onscroll(wxscrollevent &evt) {     refresh();     evt.skip(); }

...which works force redraw entire window each time. unfortunately, draws window before scroll handled, background repainted , scrolled or down, screwing alignment. documentation suggests refresh invalidates screen, meaning scroll handler must forcing redraw.

the way around can see handle scrolling code myself, i'd rather not if don't have to.

ideas, suggestions, clues...?

the general solution i've found running code after event handled post second, different event event queue before skipping current event (so gets handled default handler), , handle when comes up.

however, perusing wxwidgets source code, i've found answer specific problem: there's function, wxscrolledwindow::enablescrolling. although it's not obvious name, enable or disable "physical scrolling," forces instant redraw. calling enablescrolling(false, false); in window's constructor solves issue entirely.

c# - How to set Z index when using WPF DrawingContext? -

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

-
i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

android - layout with fragment and framelayout replaced by another fragment and framelayout -

edit: so after comments below, revisted , realized hanging me up. imagine client list , client details activity started : public class clientsmainactivity extends fragmentactivity { @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); //studiotabopenhelper db; setcontentview(r.layout.main_client_activity); } } so works great, starts main_client_activity (defined in layout below, , call activity when button on main screen clicked): intent intent = new intent(getactivity(), clientsmainactivity.class); startactivity(intent); easy issue is, clientsmainactivity not call oncreateview or anything, sets layout layout defines fragment, , listfragment. fine cause not trying pass clientsmainactivity , if have hypothetical activity like: sessionmainsactivity called when click on session edit of client, not calling sessionsmainactivity same way (starts activity sets alayout), want layout set defines...
