[code] Win32 Moving/Showing/Hiding Toolbars and Dialogs

JD Hill · 1 Oct 2010, 13:05

If you have an API which supports EnumWindows, you can use GetProcessId and GetWindowThreadProcessId to filter on windows in the current process.

But I didn't see a lag when applying the ToolWIndow class immediately after .showing the webdialog.

You got a snippet of how you applied the ToolWindow style?

thomthom · 4 Oct 2010, 15:40

'N' instead of 'L'?
hm.. I'm a wee bit confused to exactly when to use what type...

Jim · 4 Oct 2010, 16:05

From the pick-axe book:

@unknownuser said:

Strings n'' and l'' represent numbers,
i'' represent integers, p'' represents pointers to data stored in a string
``v'' represents a void type (used for export parameters only).
These strings are case-insensitive.

So I guessed you just use the type that is the best match to the API call parameters. In other words, your guess is as good as mine.

thomthom · 4 Oct 2010, 20:08

is N === L ? "Number" vs Integer? Number == Float?

I got lots of errors when I tried the Toolwindow snippet in the first post. Seems that a few constants where missing from the snippet.

I found them though, and I tried another way to get the window handle.

The code needs error checking and such.
(maybe it's because I'm not error checking yet that I some times experience that the window automatically closes after a few seconds. it has happened only sporadically...)

This prevents the window from maximising when double-clicking. Seems to introduce some frame flicker.
Can GWL_STYLE and GWL_EXSTYLE changes be combines into one call?

Can we have code blocks that expand similar to when you click on images?

Pout · 22 Oct 2010, 08:58

What are possible advantages of using toolwindows instead of webdialogs?
And is the communication between SU and the toolwindow still done in the same way?

thomthom · 22 Oct 2010, 10:38

It's not different windows - it's just different window frames. The code examples changes the window frame of webdialogs to toolwindows - which takes up less space and look neater.

Jim · 22 Oct 2010, 18:17

Thanks for following (and cleaning) up the example. Will some this be getting into TT_Lib at some point?

TT_Lib2, yes.

I already got a wrapper to create toolwindows.

Wonder if one can hook into windows like this under OSX...

For some windows, if it is a Toolwindow it will not show up in the Alt-Tab list. But this is normal for SketchUp dialog windows anyway, so there should be no difference there.

Jim · 23 Oct 2010, 04:32

@thomthom said:

It's just getting GC'd. window is a local variable referencing the WebDialog, and the variable no longer exists after the method exits. Since the WebDialog no longer has any references, it is GC'd.

@thomthom said:

Can GWL_STYLE and GWL_EXSTYLE changes be combines into one call?

Maybe - the "styles" are just bits but at different offset (one is -16, the other -20). If you meant is there a win32api function for setting both simultaneously then I don't know.

Hehe, the php highlighter work OK on Ruby.

It's just getting GC'd. window is a local variable referencing the WebDialog, and the variable no longer exists after the method exits. Since the WebDialog no longer has any references, it is GC'd.

Oh... that's a gotcha I didn't think of. You need to keep a reference to the WD for the duration of its lifespan.

The thing is - today, I don't really see any lag...

What's nice about having toolwindows is that now I can make my custom toolbar.

Just came across a nice API call that will be useful for creating webdialog toolbars:

One can use WS_EX_NOACTIVATE to prevent a window from catching focus - but from what I understand it'll still allow interaction events. I'll try it out as soon as I get home.

hm....

The WS_EX_NOACTIVATE value for dwExStyle prevents foreground activation by the system. To prevent queue activation when the user clicks on the window, you must process the WM_MOUSEACTIVATE message appropriately. To bring the window to the foreground or to activate it programmatically, use SetForegroundWindow or SetActiveWindow. Returning FALSE to WM_NCACTIVATE prevents the window from losing queue activation. However, the return value is ignored at activation time.

"queue activation"?

bleh... turns out to not be so straight forwards as I though. Seems that one needs to handle some window messages:

But working out how to handle window messages would be a very interesting thing - as then we could recreate the roll-up/down feature of SU's toolwindows.
