When does the _MDIChildGetWindow method become "fully active"?
« on: October 18, 2013, 02:03:11 pm »
I'm updating my "resize" macro to use the _MDIChildGetWindow method to set the size of the windows (buffers). This works if I enter the command manually, or if I double click a file that is opened in SE. But when I open a project (via the Project menu) I get the following error;
Code: [Select]

Adding "say" statements to the code shows that it's the _MDIChildGetWindow call that's failing. So, my question is; at what point is it OK to use that method on the _mdi.p_child object?

This is my resize.e
Code: [Select]
#include "slick.sh"
/* Macro that will automatically set all files that are opened to a specified size (see command "_buffer_add_resize()" comments for manual option.).

To use this macro:
1) the user can specify a window width, using the "Vertical line column" on the "Tools | Configuration | General", "General" tab.

-- OR --

2) the user can specify a window size for "_mdi.pchild.p_width" : please note that "Vertical line column" value must be zero (0) in order to use this option

-----------------

To change the window height, specify a different value for "_mdi.p_child.p_height" below.

Also, to specify a different location for opening the window, in the editor, change the values of "_mdi.p_child.p_x" and "_mdi.p_child.p_y" below.

To load the 'resize.e' macro file:

 *  Select "Macro | Load Module"
 *  Choose the 'resize.e' macro file from the browse.
 *  Click on the "Open" button
 *  You will see the message "Module(s) loaded" on the editor's message line.

Bump. Any SE folks on here that can answer my question? Please. Pretty please with a cherry on top.  ;D

This is an invalid call:

Code: [Select]
curChild._MDIChildGetWindow( curX, curY, curWidth, curHeight );

Can't call windowId._MDIChildGetWindow.
Must call _mdi._MDIChildGetWindow.

By the way, double clicking any line in the stack error window jumps to that exact spot in the code.  That might be easier than adding a bunch of say() statements.

Hmm, the macro works just fine once the Project is open when I enter it in the command line. It sure seems like a timing issue.

Yeah, sorry, I misread the line.

_MDIClientGetWindow is only valid on _mdi.
_MDIChildGetWindow is valid on a windowId.

Try using _post_call() to work around this.  I'm not sure I'd expect the window to be ready yet during an initial _add_buffer callback, and the _post_call function is typically a good way to handle this kind of situation.

Code: [Select]
/**
 * Posts a calls to the Slick-C&reg; function corresponding to name table
 * index, proc_index, and optional passes the first argument, arg1.  The
 * call is made after the editor returns to a message loop.  This function
 * should only be used under circumstances where an operation can not be
 * performed immediately.  The dialog editor uses this function to display
 * error message boxes during on_lost_focus events.  During the
 * on_got_focus and on_lost_focus events you can not display a dialog box.
 * Use find_index to get an index to a global function.
 *
 * @param pfnCallback         pointer to function to call
 * @param CallbackArgument    argument to pass to function
 *
 * @categories Miscellaneous_Functions
 */
int _post_call(typeless pfnCallback,_str CallbackArgument=null);

I changed the macro to use _post_call( resize_window ) which sorta works. I say sorta because all the windows appear to be "processed" (at least they're opened) but I still get errors. The error message only includes this line in the stack window;
resize.ex 81 resize_window()   p_window_id: 90   p_object: OI_FORM   p_name:
and it is followed by 4 (sometimes 2) message boxes (regardless of how many fields in the project are being opened) that says basically the same thing. I don't get the level of detail I originally reported. Double clicking the error line just says file resize.e not found. Maybe that's because I have the macro in my own directory and not the default location.

So, some progress but still not quite right.

Probably the reason SE finds the macro files for me is because in the VSLICK.INI file I set VSLICKINCLUDE, VSLICKMACROS, and VSLICKPATH to all include the directories where I keep my macros.  If you do that then I would expect clicking in the stack form to work (and probably various other things will work better as well).

Sorry I can't take a more hands-on approach to helping you debug the macro right now.

One thing I do see offhand is that resize_window with no arguments acts on the current window.  Did you make changes so the deferred calls via _post_call know which window to act on?
