PhClipboardRead()

Copy data from the clipboard

Synopsis:

typedef char PhClipType[8];

PhClipboardHdr *PhClipboardRead(unsigned short ig,
                                PhClipType type);

Arguments:

ig

The input group. Each input group has its own private clipboard. To determine the current input group, call PhInputGroup(), passing to it the event that triggered the clipboard operation (e.g. cbinfo->event).

type

The data type to read from the clipboard.

Library:

ph

Description:

This function copies the clipboard data in that matches type from the Photon clipboard, and returns a pointer to the data populated in a PhClipboardWrite structure.

Returns:

A pointer to a populated PhClipboardWrite

Successful completion.

NULL

An error occurred.

Examples:

This callback reads data from the clipboard, and pastes it in a PtText widget named text:

int
paste_from_clip( PtWidget_t *widget, ApInfo_t *apinfo, PtCallbackInfo_t *cbinfo )

{
    int *cursor, ig, insertion_pt;
    PhClipboardHdr *ptr;

    ig=PhInputGroup(cbinfo->event);

    PtGetResource(ABW_text, Pt_ARG_CURSOR_POSITION, &cursor, 0);
    insertion_pt=*cursor;

    if (ptr=PhClipboardRead(ig,Ph_CLIPBOARD_TYPE_TEXT))
    {
        PtTextModifyText(ABW_text, insertion_pt, insertion_pt,
            insertion_pt, ptr->data, utf8strblen( ptr->data, ptr->length, NULL ) );
        free(ptr->data);
        free(ptr);
    }

    PtContainerGiveFocus(ABW_text,NULL);
    return(Pt_CONTINUE);

}
