Fx:Init Fx_Menubar Fx_Frame Fx_Entry
For example, suppose you have the following Schema.
# Sample MyRelation/Schema file
a ( b c d )*
An Fx toolkit program for this Schema might look like:
#!/usr/local/qddb/bin/qwish -f
lappend auto_path $qddb_library/fx $blt_library
set s [qddb_schema open MyRelation]
# You *must* call Fx:Init $s to initialize Fx
Fx:Init $s
Fx_Menubar menubar -w .mb -schema $s -array gv_attr
set search_entry [menubar SearchForEntry]
# define all the instances and how they are viewed.
# -setschema should be set on the first
# call to Fx_Entry and Fx_Frame
Fx_Frame a -w .a -setschema $s -attr a -side top \
-anchor nw -relief raised
Fx_Entry a.b -w .a.b -searchfor_entry $search_entry -attr a.b \
-relief sunken -bd 3 -side left -setschema $s
# configure the Fx_Frame's focus (for adding new entries)
a configure -focus [a.b GetEntry]
Fx_Entry a.c -w .a.c -attr a.c -relief sunken -bd 3 -side left
pack .a.b -side left -expand on -fill x
pack .a.c -side left -expand on -fill x
# Note that a.d doesn't have to be in the same physical frame as
# its siblings in the Schema.
Fx_Entry d -w .d -attr a.d -relief sunken -bd 3 -side left
pack .d -side bottom -expand on -fill x
# Link up the frames and entries with the menubar
menubar configure -instances [Fx_Entry::GetInstances] \
-frames [Fx_Frame::GetInstances]
# Go to Search Mode to start
menubar SearchModeProc
Fx:InitConfigure ;# sets up window position management
