Hmm, then user need to resize forms constantly by himself...
How it can happen if I set client height of form to 200, but it actually
set to 190?
There are several problems.
Some window managers define the width and height including the border,
some
without, and there is no easy way to find out. It seems getting better, so
at least it works under the most common wm.
Then come the hen and the egg problem: To determine the needed
ClientHeight,
you need the theme and the font size, which needs the Handle, which needs
the ClientHeight.
And some window managers do not allow free resizing of windows, only in
non
'ugly' steps.
And last but not least: Calculating the correct ClientHeight can depend on
a
lot of data, which a LCL interface may not have implemented yet for all
cases. The gtk and win32 interfaces are getting stable and complete, but
we
already get three new interfaces: qt, wince and carbon.
Of course programmers don't want to wait years, until these interfaces get
the state of the gtk/win32 interfaces. Programmers want to use the IDE and
the LCL with their favorite interfaces, even if there are some ugly todos.
I see the following solution: try to implement IDE dialogs as good as
possible for every interface.
It is not wise to make IDE to look bad for all interfaces because interface
Y has some problems. For example, even if only interface Z allow to make
something better, do it only for interface Z (by using ifdefs or something
else).
Experiments are needed. I can take 2 IDE forms (simple-nonresizable and
complex-resizable) and try to make them as good as possible. Then they will
be tested on different interfaces and window managers to find any problems
and try to fix them.
I hope things are not so bad :)
Compiler options is a good candidate for complex form. It need to be
converted in lfm in any case.
Any good candidate for simple dialog?
