#Locating Dialogs
9 messages in this thread
Does anyone know how to create an IPAS4 function to position a dialog anywhere
on the screen? I'm looking for something similar to center_dialog() but with
some added functionality like: put_dialog_at(x,y) where x,y is the new
location of the dialog box.
Alfonso
P.S. I tried modifying the Dialog structure, but this didn't work.
Hi Alfonso,
<< put_dialog_at(x,y) where x,y is the new location of the dialog box. >>
I don't know of any uploaded code to do this.

Jonas,
A while back I was talking to you about *not* having the dialog boxs centered
with Keyscript. I think the "put_dialog_at(x,y)" would be a good thing to put
on the IPAS5 wishlist.
Mark
I agree. If you have viewports that need to be displayed at the same time as
the dialog, a function such as put_dialog_at(x,y) is needed badly.
Alfonso
Hi Mark,
<< "put_dialog_at(x,y)" would be a good thing to put on the IPAS5 wishlist. >>
got it.
Jonas:
I developed this code to handle the dialog location. I have to thank Stefan
Didak who gave me a hint on how to code it.
// assumptions:
// 1) Dialog was created with upper left corner at origin
// 2) center of Dialog will be positioned to the right @
// X = MAXX + (MAXX-MAXY)/2 = MAXY/2
// Y = (MAXY – dialog[0].height)/2
//
// If someone has the time and patience, please make this function more
general
// like locate_dialog_at(x,y) where x,y are the upper left corner
coordinates of the
// dialog.
int MAXX, MAXY; // maximum coordinates in X and Y, GLOBAL VARIABLES!!!
void Do_User_Interface(void) {
ScrnInfo screen;
init_dialog( maindlg, main_edit, NULL);
ready_dialog ( maindlg, main_edit, NULL, main_feel, main_rad, NULL, NULL
);
gfx_scrn_info(&screen);
MAXX = screen.sc_width;
MAXY = screen.sc_height;
center_dialog( maindlg );
locate_dialog( maindlg );
gfx_clearscreen();
gfx_cblock(0,0,MAXX,MAXY,6); // fill whole screen
draw_dialog( maindlg );
do_dialog ( maindlg, -1 );
gfx_redraw();
}
// The code that does the trick!
// by Alfonso Hermida
void locate_dialog(Dialog *root) {
int max, start=0, i;
max = dlg_item_count(root,start);
root[0].sx += MAXY/2;
root[0].sy = (MAXY – root[0].height)/2;
for(i=start;i<max;i++) {
root[i].sx = root[i].x + root[0].sx;
root[i].sy = root[i].y + root[0].sy;
}
}

Thanks Alfonso!
<< cool post.. >>
I'll use your post the next time someone asks this question.
Thanks again..

I forgot to explain what I use it for, so it will be easier
to understand the code. If you have 4 viewports on the screen
(screen dimensions are MAXX and MAXY) the area to your right which
is empty has the dimensions (assume the viewports are square and of
size MAXY/2,MAXY/2) horiz = MAXX-MAXY vert = MAXY
The code that I sent you locates a dialog that is already centered so
that the center of the dialog is on the center of the empty area
(that which is not covered by the viewports).
Does it make any sense????
Hi Alfonso,
<< Does it make any sense???? >>
sure it does..
