I have a panel with a sizer and a whole column of buttons. I want the panel to become scrollable, rather than partially disappearing, when the window is resized (made smaller). What's the easiest way to achieve this? I tried adding the scroll bit to the panel which creates the vertical scrollbar but...

Yes, as weird as this sounds. When I open file explorer on Windows 7 (clicking My Computer on the start menu), my wxwidgets app windows get refreshed (flickers momentarily) and 1 of them doesn't even paint it's background (wxPanels)correctly on this particular refresh even and leaves it looking terr...

I traverse the tree and expand the node. This makes the control scroll down to the bottom of the tree. I want to move it back to the top. I tried ScrollTo(m_root_id) but that doesn't do it. How do I go about this?

Nice one! Any more? Seriously, anything to beautiful it is cool. I know there was an extensive library with preference window and such. But I can't find it via google. Probably went belly up.

PB wrote:wxRegion::Intersect(wxRect&) appears to be there in in wxWidgets 2.8 and wxWidgets 2.9?

That function creates a region that intersects both (or something). It doesn't actually tell you if region and rect intersect.

I remember years ago someone posted screenshots of their widget library for wxWidgets. It had a bunch of stuff and it looked really nice (like office if I remember). Is that guy/company still around? Are there commercial custom widgets? These stock ones are getting bland.. I'd love move eye candy!

I need to know if a region intersects a rectangle. There doesn't seem to be an intersects() function in wxRegion. I can do wxRegion().GetBox() but a box isn't fine grained enough. Anyone know how to know if a wxRect intersects a wxRegion?

Ok, so using wxFormBuilder I layout my dialog windows. But, then I have to write all the XRC glue code by hand. A pain in the ass. wxFormbuilder will give you the C++ files but with XRC it gives you just the xrc file and nothing else. Shouldn't it give you the C++ glue code with all the events wired...

m_tree_control->Expand(id); [...] ExpandAllNodes(); [...] CollapseAllNodes(); [...] m_tree_control->SortChildren(m_root_id); Maybe you should call these methods after you added all items and not for each item. Also, try wrapping the whole item creating into Freeze()/Thaw() You my friend are a geniu...

When appending items to a wxtreectrl it takes forever. If I have about 350 "rows" in a tree it'll take > 10 seconds on my 2.53 ghz core 2 duo machine. Is there any way to make it take less? Like 10 seconds less? Here's the function that adds entries to the tree. It gets called repeatedly to add all ...

It is multi threaded but the second thread isn't a problem. It's falling into heavy calculations and not yielding. Adding wxYieldIfNeeded has helped so I'm tempted to go into all the heavy parts (main thread) and just sprinkle the call in liberally. Any downsides?

I want to add a second tree control so when the first one runs out of space for entries it "spills over" into another one. Is this possible? I'd have to know when the first tree ctrl is "full" so I can populate the next. Can this be done?

My program is stuttering. Adding calls to wxYieldIfNeeded helps. Is there a downside to liberally sprinkling this throughout the code? Should I use some reserve? Are there any cost benefit analysis I should be doing?

I want to know when the user clicks the title bar and drags the window around. The activation of the window because of the click doesn't matter to me. I want to knock what his mouse is doing when he clicks and holds and drags the window (wxframe) around. Can this be had?

Thanks for the help but it didn't work. My code, I think, is right. So it looks like this: Hello world Button->Spacer->Help Button->Back Button->Next Button I'm gussing the spacer expands so the hello world button is left justified. The rest of the buttons right justified. Reversing it gives: Spacer...
