MSEide+MSEgui Pascal Cross Platform GUI Development System

2024-04-13 Version 5.10.4. Copyright (c) 1999-2024 by Martin Schreiber and friends.

MSEgui is a complete independent Free Pascal widgetset. It does not use any other widgetsets like GTK2/GTK3/Qt4/Qt5. MSEgui interacts on Unix directly with X11 server (like other widgetsets do). On Windows, it deals with the low level Windows GDI interface.

MSEgui is like a GTK2/GTK3/Qt5 widgetset with same look-and-feel on each OS (Linux, FreeBSD, OpenBSD, NetBSD, MacOS and Windows). And because it is developed in Pascal, you have full control on the widgetset.

 Change the used fonts. Example for a 16 pixel height default font:
 --FONTALIAS=stf_default,,16

--NOZEROLINES
 Use 1-width lines instead of 0-width lines. X11 only. Workaround for buggy HW-accelerated
 X-servers which don't draw lineends exactly. Can degrade performance, see
 https://bugzilla.opensuse.org/show_bug.cgi?id=1021803

--NOZORDERHANDLING
 Do not touch Z-order of the windows.

--NORESTACKWINDOW
 Do not use the NET_RESTACK_WINDOW protocol.

--NORECONFIGUREWMWINDOW
 Do not use xreconfigurewmwindow() for window stacking operation.

--RECONFIGUREWMWINDOW
 Use xreconfigurewmwindow() for window stacking operation.

--STACKMODEBELOWWORKAROUND
 Necessary for windowmanagers with buggy xreconfigurewmwindow() handling.

--NOSTACKMODEBELOWWORKAROUND
 No workaround.

--TOPLEVELRAISE

Antialiased text with MSEgui 32 bit on 64 bit Linux

MSEgui uses Xft for antialiased fonts on Linux. Please install lib32-libxft package if necessary.

Popup widgets behind the forms

If the popup widgets are showed behind the forms, try to start the MSEgui program with the option '--TOPLEVELRAISE'. Do not use this option if is not necessary (KDE, Gnome... work well without).

Display problems with Linux radeon and other EXA drivers

If the display is distorted or slow add Option "EXAPixmaps" "off" to Section "Device" of xorg.conf, see https://bugs.freedesktop.org/show_bug.cgi?id=69543 https://bugs.freedesktop.org/show_bug.cgi?id=84253 or use the proprietary video driver for your video chip.

Flashing taskbar widgets in IceWM

Newer revisions of IceWM let the taskbar icons of MSEgui applications flash. Start the MSEgui application with the option '--TOPLEVELRAISE'.

Invalid inputmanager for Ubuntu

The utf-8 setup in Ubuntu seems to be incomplete. If you get the exception "egui : Invalid inputmanager tinternalapplication ." at program start, try to replace your language locale in /usr/share/X11/locale/locale.dir by en_US as a workaround. Example for ru_RU.UTF-8: replace ru_RU.UTF-8/XLC_LOCALE ru_RU.UTF-8 by en_US.UTF-8/XLC_LOCALE ru_RU.UTF-8

Wrong window positions for Ubuntu 14.04

Window positions in Unity are wrong because the Ubuntu windowmanager does not support static_gravity: http://askubuntu.com/questions/451903/wingravity-static-gravity-not-suppo https://bugs.launchpad.net/ubuntu/+bug/1312044 http://askubuntu.com/questions/457456/wingravity-static-gravity-not-supported-in-14-04

How to add custom components to MSEide

There is a project 'apps/myide/mymseide.prj' as a demo. Start MSEide, open project 'apps/myide/mymseide.prj', 'Project'-'Build', 'Target'-'Continue', the IDE with the new component 'tmybutton' will be compiled and started in the the debugger. Binary name is 'mymseide' (linux) or 'mymseide.exe' (win32).

If you wish to do it from scratch:

• Create a register unit for your components (see 'apps/myide/regmycomps.pas' for an example).
• Enter the unitname followed by a comma ('myregunit,' if your regunitfile is 'myregunit.pas') in a file named 'regcomponents.inc'.
• Build the IDE with -dmorecomponents as option.

Component units integrated by this mechanism don't need to be GPL, see apps/ide/COPYING.IDE

If you want to add custom icons to your components:

• Convert 2424 pixel BMP or PNG files with tools/bmp2pas to an icon unit ('_bmp.pas').
• Add the name of the icon unit to 'uses' in your register unit.

How to run i18ndemo

- Start MSEide.
- 'Project'-'Open'-'yourdirectory/msegui/apps/i18ndemo/i18ndemo.prj'.
- 'Project'-'Make' to create the rsj files.
- 'Project'-'Open'-'yourdirectory/msegui/tools/i18n/msei18n.prj'.
- 'Target'-'Continue'.

In MSEi18n:

 - Adjust 'Settings'-'Configure MSEi18n'-'${MSEDIR}' and ${COMPILER}.
 - 'Open'-'yourdirectory/msegui/apps/i18ndemo/i18ndemo.trp'
 - 'Make'.
 - Close message window.
 - Close MSEi18n.
 - 'Project'-'Open'-'yourdirectory/msegui/apps/i18ndemo/i18ndemo.prj'.
 - 'Target'-'Continue'.

ZeosLib

Since msegui commit fbbaa979b, ZeosLib components are included in mseide by default. Also last stable source are included in /mseide-msegui/lib/common/mzeoslib/.

If you want to use other ZeosLib source, you need to delete directory /mseide-msegui/lib/common/mzeoslib/. Then add the path to the ZeosLib source to 'Project'-'Options'-'Make'-'Directories' and compile your applicatio with '-dMSEgui'.

If you want to recompile the IDE with new ZeosLib source, add parameter '-dmse_with_zeoslib -dMSEgui'. There is a predefined IDE project apps/ide/mseide_zeos.prj, update 'Project'- 'Options'-'Macros' according to your installation.

Crosscompiling and remote debugging i386/x84_64-linux -> arm-linux

For Raspberry Pi:

• Establish a ssh login without password (public key authentication).

On the i386/x84_64-linux host:

• install the scp program

• download and extract https://sourceforge.net/projects/mseide-msegui/files/fpcrossarm/crossfpc-i386_linux_eabihf_3_0_5.tar.gz (or crossfpc-x86_64_linux_eabihf_3_0_5.tar.gz) to .

• Start MSEide, in 'Settings'-'Configure MSEide'-'Global Macros' add:

Name Value

CROSSMSEDIR <MSEide+MSEgui directory> CROSSFPCDIR CROSSFPCVERSION 3.0.5 HOSTIP REMOTEIP REMOTEPORT <the remote port, ex: 2345> REMOTEUSER pi

• 'Project'-'New'-'From Template', select "crossarmdefault.prj" or "crossarmconsole.prj".
• Create the new project.
• 'Project'-'Options'-'Macros', set the TARGETPROJECTDIR value to the project path in remote target, ex: "/home/pi/proj/testcase".
• Check the TARGETENV macro.
• If your application needs additional libraries copy them from Raspberry Pi /lib/arm-linux-gnueabihf or /usr/lib/arm-linux-gnueabihf to /eabihf/lib

Press F9 and hope the best. ;-)

If there is a debugger timeout at startup enlarge the 'Project'-'Options'-'Debugger'-'Target'-'Wait before connect' value.

Have a lot of fun!
