# Requesters — EasyRequest, AutoRequest, ASL File Requester
|
|
|
|
## Overview
|
|
|
|
Requesters are modal dialog boxes. Intuition provides `EasyRequest` for simple dialogs; `asl.library` provides file/font/screen-mode requesters.
|

|
|
## EasyRequest (OS 2.0+)
|
|
|
|
```c
|
|
struct EasyStruct es = {
|
|
sizeof(struct EasyStruct),
|
|
0,
|
|
"Warning", /* title */
|
|
"Delete file '%s'?", /* body (printf format) */
|
|
"Yes|No|Cancel" /* button labels (| separated) */
|
|
};
|
|
|
|
LONG result = EasyRequest(win, &es, NULL, filename);
|
|
/* Returns: 1=Yes, 0=Cancel, 2=No (rightmost non-zero, leftmost=0) */
|
|
/* For Yes|No: 1=Yes, 0=No */
|
|
```
|
|

|
## ASL File Requester
|
|
|
|
```c
|
|
struct Library *AslBase = OpenLibrary("asl.library", 39);
|
|
struct FileRequester *fr = AllocAslRequestTags(ASL_FileRequest,
|
|
ASLFR_TitleText, "Open File",
|
|
ASLFR_InitialDrawer, "SYS:",
|
|
ASLFR_InitialPattern, "#?.txt",
|
|
ASLFR_DoPatterns, TRUE,
|
|
TAG_DONE);
|
|
|
|
if (AslRequest(fr, NULL)) {
|
|
Printf("Selected: %s%s\n", fr->fr_Drawer, fr->fr_File);
|
|
}
|
|
FreeAslRequest(fr);
|
|
CloseLibrary(AslBase);
|
|
```

## ASL Font Requester
|
|
|
|
```c
|
|
struct FontRequester *fo = AllocAslRequestTags(ASL_FontRequest,
|
|
ASLFO_TitleText, "Select Font",
|
|
ASLFO_InitialName, "topaz.font",
|
|
ASLFO_InitialSize, 8,
|
|
ASLFO_DoStyle, TRUE,
|
|
TAG_DONE);
|
|
|
|
if (AslRequest(fo, NULL)) {
|
|
Printf("Font: %s %ld\n", fo->fo_Attr.ta_Name, fo->fo_Attr.ta_YSize);
|
|
}
|
|
FreeAslRequest(fo);
|
|
```
