The user can select a new directory to examine by scrolling
through the list of directories and selecting the desired
directory or by editing the directory mask. Selecting a new
directory from the directory list does not change the search
pattern. A user can select a new search pattern by editing
the directory mask or, when the FileSelectionBox has the
optional XXXXmmmmNNNNppppaaaatttthhhhMMMMooooddddeeee XXXXmmmmPPPPAAAATTTTHHHH____MMMMOOOODDDDEEEE____RRRREEEELLLLAAAATTTTIIIIVVVVEEEE display, the
filter text field. Double clicking or pressing KKKKAAAAccccttttiiiivvvvaaaatttteeee on
a directory in the directory list initiates a search for
files and subdirectories in the new directory, using the
current search pattern.
The user can select a file by scrolling through the list of
filenames and selecting the desired file or by entering the
filename directly into the text edit area. Selecting a file
from the list causes that filename to appear in the file
selection text edit area.
The user may select a new file as many times as desired.
The application is not notified until the user takes one of
the following actions:
+o Selects the _O_K PushButton
+o Presses KKKKAAAAccccttttiiiivvvvaaaatttteeee while the selection text edit area
has the keyboard focus
+o Double clicks or presses KKKKAAAAccccttttiiiivvvvaaaatttteeee on an item in the
file list
FileSelectionBox initiates a directory and file search when
any of the following occurs:
+o The FileSelectionBox is initialized
+o The function XXXXttttSSSSeeeettttVVVVaaaalllluuuueeeessss is used to change XXXXmmmmNNNNddddiiiirrrrMMMMaaaasssskkkk,
XXXXmmmmNNNNddddiiiirrrreeeeccccttttoooorrrryyyy, XXXXmmmmNNNNppppaaaatttttttteeeerrrrnnnn, or XXXXmmmmNNNNffffiiiilllleeeeTTTTyyyyppppeeeeMMMMaaaasssskkkk
+o The user activates the FFFFiiiilllltttteeeerrrr PushButton
+o The user double clicks or presses KKKKAAAAccccttttiiiivvvvaaaatttteeee on an item
in the directory list
+o The application calls XXXXmmmmFFFFiiiilllleeeeSSSSeeeelllleeeeccccttttiiiioooonnnnDDDDooooSSSSeeeeaaaarrrrcccchhhh
+o The user presses KKKKAAAAccccttttiiiivvvvaaaatttteeee while the directory mask

When a file search is initiated, the FileSelectionBox takes
If the input _p_a_t_t_e_r_n is NULL, the procedure
constructs the output _p_a_t_t_e_r_n as follows: If the
input _m_a_s_k member is NULL, the procedure uses the
widget's XXXXmmmmNNNNppppaaaatttttttteeeerrrrnnnn as the output _p_a_t_t_e_r_n;
otherwise, it extracts the output _p_a_t_t_e_r_n from the
input _m_a_s_k. If the resulting output _p_a_t_t_e_r_n is
empty, the procedure uses a pattern that matches
all files instead.
The data qualification procedure constructs the
output _m_a_s_k from the output _d_i_r and _p_a_t_t_e_r_n. The
procedure must ensure that the output _d_i_r,
_p_a_t_t_e_r_n, and _m_a_s_k are fully qualified.
If the input _v_a_l_u_e member is not NULL, the
procedure must copy it to the output _v_a_l_u_e member;
otherwise, the procedure must copy the widget's
XXXXmmmmNNNNddddiiiirrrrSSSSppppeeeecccc to the output _v_a_l_u_e.
The data qualification procedure must calculate
the lengths of the output _v_a_l_u_e, _m_a_s_k, _d_i_r, and
_p_a_t_t_e_r_n members and must fill in the corresponding
length members of the output callback struct.
The data qualification procedure must copy the
input _r_e_a_s_o_n and _e_v_e_n_t members to the
corresponding output members.
