Okay, I've done some changes at Fl_Menu_.cxx:
I deleted the whole line 330:
At line 797 there starts a block of code "make sure all the menus..."
(it ends at line 802) and I replaced the whole block by the following:
int w_menu= 0;
for (int k = menubar; k < pp.nummenus; k++)
{
w_menu+= pp.p[k]->w();
if (!pp.p[k]->shown())
{
if (pp.p[k]->title) pp.p[k]->title->show();
pp.p[k]->show();
}
}
if (pp.nummenus)
{
int scr_x, scr_y, scr_w, scr_h;
Fl::screen_xywh(scr_x, scr_y, scr_w, scr_h);
int rx= 0;
if (X + w_menu > scr_x + scr_w) rx= scr_x + scr_w;
// Start relocation at screen border
else if (X!= pp.p[0]->x()) rx= X + w_menu;
// Relocate back to origin
if (rx) for (int menu= pp.nummenus -1; menu > -1; --menu)
{ // menu structure must be relocated
rx-= pp.p[menu]->w();
pp.p[menu]->position(rx, pp.p[menu]->y());
}
}
This code can be optimised for example by moving Fl::screen_xywh()
before the for-ever-loop and "if (pp.nummenus)" can be enlarged to check
for change of number of menus, but to show the effect it is better to
present just one code block.
The moving to the left seems okay to me, but the relocation to the
origin maybe should be changed to observe only case of left menu side
leaving screen, because this way the menu jumps and leaves mouse cursor.
What do you think of this?
