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

Jim

Turns out the negative return value is not a problem - I just wasn't using it right.

Jim

Maybe the .show event of the dialog triggers as it's displayed? But I'm not sure if it wait for the HTML - which you do not want - as that will lag.

And can you do anything before calling show? You need a handle to the window - how are you getting that at the moment?

Using FindWindow - which is a basic search by window name and class.

Jim

For a WebDialog, I couldn't find a handle until it was shown. I used EnumWindows and EnumChildWidows to locate it.

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

thomthom

Neat!

Jim

The Win32API.so file does not support the use of callbacks needed by EnumWindows and EnumChildWindows. So I have had to move to win32/api.so, which does support callbacks. But this will also allow more interesting things to be done, such as finding resizing Sketchup by its drawing area, and sending values to the Measurements box via a plugin.

thomthom

When there is multiple SketchUp windows open - how do you find the one you want?

Jim

Hopefully, the window titles are different. If not, I'm not sure.

thomthom

So you look for windows with "<filename> - SketchUp (Pro)"

Jim

Too fast... here's how to get the exact name. (But is_pro? is for windows 7+)


def su_window_name
    pro = Sketchup.is_pro? ? " Pro" ; ""
    if ((title = Sketchup.active_model.title).empty?)
        return ("Untitled - SketchUp" + pro)
    else
        return (title += ".skp - SketchUp" + pro)
    end
end

thomthom

But when there is two untitled windows there could be problems?

Jim

Yes, but in that case how would any program know which one the user meant?

You can find all of the matching windows. It's just hard to know which the user meant to use.

@jim said:

If you'd created the window then you'd get the handle from there. (Would be nice if the API could expose the handles in the Ruby API)

I suppose that if it is possible to get an array of matching windows one could filter out the window you want by checking if one of them is the active - if it's the active SU window you want. (Assuming SU is the currently active window)
Or maybe by Z-Order? Assuming that the top most is the most recent - again if that is what you want...

thomthom

In most cases you'd get the window the user is working on, right?
So how about
GetForegroundWindow - then, in case one of the toolbars or webdialogs are the active window, iterate down the hierarchy using GetParent - checking for matching window title?

JD Hill

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

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

thomthom

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

Jim

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

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

thomthom

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?
