SearchEntry

#GtkSearchEntry is a subclass of #GtkEntry that has been tailored for use as a search entry.

It will show an inactive symbolic “find” icon when the search entry is empty, and a symbolic “clear” icon when there is text. Clicking on the “clear” icon will empty the search entry.

Note that the search/clear icon is shown using a secondary icon, and thus does not work if you are using the secondary icon position for some other purpose.

To make filtering appear more reactive, it is a good idea to not react to every change in the entry text immediately, but only after a short delay. To support this, #GtkSearchEntry emits the #GtkSearchEntry::search-changed signal which can be used instead of the #GtkEditable::changed signal.

The #GtkSearchEntry::previous-match, #GtkSearchEntry::next-match and #GtkSearchEntry::stop-search signals can be used to implement moving between search results and ending the search.

Often, GtkSearchEntry will be fed events by means of being placed inside a #GtkSearchBar. If that is not the case, you can use gtk.search_entry.SearchEntry.handleEvent to pass events.

Functions

connectNextMatch gulong connectNextMatch(T callback, Flag!"After" after): Connect to NextMatch signal.
connectPreviousMatch gulong connectPreviousMatch(T callback, Flag!"After" after): Connect to PreviousMatch signal.
connectSearchChanged gulong connectSearchChanged(T callback, Flag!"After" after): Connect to SearchChanged signal.
connectStopSearch gulong connectStopSearch(T callback, Flag!"After" after): Connect to StopSearch signal.
handleEvent bool handleEvent(gdk.event.Event event): This function should be called when the top-level window which contains the search entry received a key event. If the entry is part of a #GtkSearchBar, it is preferable to call gtk.search_bar.SearchBar.handleEvent instead, which will reveal the entry in addition to passing the event to this function.
self SearchEntry self(): Returns this, for use in with statements.

progressPulse void progressPulse(): Indicates that some progress is made, but you don’t know how much. Causes the entry’s progress indicator to enter “activity mode,” where a block bounces back and forth. Each call to gtk.entry.Entry.progressPulse causes the block to move by a little bit (the amount of movement per pulse is determined by gtk.entry.Entry.setProgressPulseStep).
resetImContext void resetImContext(): Reset the input method context of the entry if needed.
setActivatesDefault void setActivatesDefault(bool setting): If setting is true, pressing Enter in the entry will activate the default widget for the window containing the entry. This usually means that the dialog box containing the entry will be closed, since the default widget is usually one of the dialog buttons.
setAlignment void setAlignment(float xalign): Sets the alignment for the contents of the entry. This controls the horizontal positioning of the contents when the displayed text is shorter than the width of the entry.
setAttributes void setAttributes(pango.attr_list.AttrList attrs): Sets a #PangoAttrList; the attributes in the list are applied to the entry text.
setBuffer void setBuffer(gtk.entry_buffer.EntryBuffer buffer): Set the #GtkEntryBuffer object which holds the text for this widget.
setCompletion void setCompletion(gtk.entry_completion.EntryCompletion completion): Sets completion to be the auxiliary completion object to use with entry. All further configuration of the completion mechanism is done on completion using the #GtkEntryCompletion API. Completion is disabled if completion is set to null.
setCursorHadjustment void setCursorHadjustment(gtk.adjustment.Adjustment adjustment): Hooks up an adjustment to the cursor position in an entry, so that when the cursor is moved, the adjustment is scrolled to show that position. See gtk.scrolled_window.ScrolledWindow.getHadjustment for a typical way of obtaining the adjustment.
setHasFrame void setHasFrame(bool setting): Sets whether the entry has a beveled frame around it.
setIconActivatable void setIconActivatable(gtk.types.EntryIconPosition iconPos, bool activatable): Sets whether the icon is activatable.
setIconDragSource void setIconDragSource(gtk.types.EntryIconPosition iconPos, gtk.target_list.TargetList targetList, gdk.types.DragAction actions): Sets up the icon at the given position so that GTK+ will start a drag operation when the user clicks and drags the icon.
setIconFromGicon void setIconFromGicon(gtk.types.EntryIconPosition iconPos, gio.icon.Icon icon): Sets the icon shown in the entry at the specified position from the current icon theme. If the icon isn’t known, a “broken image” icon will be displayed instead.
setIconFromIconName void setIconFromIconName(gtk.types.EntryIconPosition iconPos, string iconName): Sets the icon shown in the entry at the specified position from the current icon theme.
setIconFromPixbuf void setIconFromPixbuf(gtk.types.EntryIconPosition iconPos, gdkpixbuf.pixbuf.Pixbuf pixbuf): Sets the icon shown in the specified position using a pixbuf.
setIconFromStock void setIconFromStock(gtk.types.EntryIconPosition iconPos, string stockId): Sets the icon shown in the entry at the specified position from a stock image.
setIconSensitive void setIconSensitive(gtk.types.EntryIconPosition iconPos, bool sensitive): Sets the sensitivity for the specified icon.
setIconTooltipMarkup void setIconTooltipMarkup(gtk.types.EntryIconPosition iconPos, string tooltip): Sets tooltip as the contents of the tooltip for the icon at the specified position. tooltip is assumed to be marked up with the [Pango text markup language]PangoMarkupFormat.
setIconTooltipText void setIconTooltipText(gtk.types.EntryIconPosition iconPos, string tooltip): Sets tooltip as the contents of the tooltip for the icon at the specified position.
setInnerBorder void setInnerBorder(gtk.border.Border border): Sets entry’s inner-border property to border, or clears it if null is passed. The inner-border is the area around the entry’s text, but inside its frame.
setInputHints void setInputHints(gtk.types.InputHints hints): Sets the #GtkEntry:input-hints property, which allows input methods to fine-tune their behaviour.
setInputPurpose void setInputPurpose(gtk.types.InputPurpose purpose): Sets the #GtkEntry:input-purpose property which can be used by on-screen keyboards and other input methods to adjust their behaviour.
setInvisibleChar void setInvisibleChar(dchar ch): Sets the character to use in place of the actual text when gtk.entry.Entry.setVisibility has been called to set text visibility to false. i.e. this is the character used in “password mode” to show the user how many characters have been typed. By default, GTK+ picks the best invisible char available in the current font. If you set the invisible char to 0, then the user will get no feedback at all; there will be no text on the screen as they type.
setMaxLength void setMaxLength(int max): Sets the maximum allowed length of the contents of the widget. If the current contents are longer than the given length, then they will be truncated to fit.
setMaxWidthChars void setMaxWidthChars(int nChars): Sets the desired maximum width in characters of entry.
setOverwriteMode void setOverwriteMode(bool overwrite): Sets whether the text is overwritten when typing in the #GtkEntry.
setPlaceholderText void setPlaceholderText(string text): Sets text to be displayed in entry when it is empty and unfocused. This can be used to give a visual hint of the expected contents of the #GtkEntry.
setProgressFraction void setProgressFraction(double fraction): Causes the entry’s progress indicator to “fill in” the given fraction of the bar. The fraction should be between 0.0 and 1.0, inclusive.
setProgressPulseStep void setProgressPulseStep(double fraction): Sets the fraction of total entry width to move the progress bouncing block for each call to gtk.entry.Entry.progressPulse.
setTabs void setTabs(pango.tab_array.TabArray tabs): Sets a #PangoTabArray; the tabstops in the array are applied to the entry text.
setText void setText(string text): Sets the text in the widget to the given value, replacing the current contents.
setVisibility void setVisibility(bool visible): Sets whether the contents of the entry are visible or not. When visibility is set to false, characters are displayed as the invisible char, and will also appear that way when the text in the entry widget is copied elsewhere.
setWidthChars void setWidthChars(int nChars): Changes the size request of the entry to be about the right size for n_chars characters. Note that it changes the size request, the size can still be affected by how you pack the widget into containers. If n_chars is -1, the size reverts to the default entry size.
textIndexToLayoutIndex int textIndexToLayoutIndex(int textIndex): Converts from a position in the entry contents (returned by gtk.entry.Entry.getText) to a position in the entry’s #PangoLayout (returned by gtk.entry.Entry.getLayout, with text retrieved via pango.layout.Layout.getText).
unsetInvisibleChar void unsetInvisibleChar(): Unsets the invisible char previously set with gtk.entry.Entry.setInvisibleChar. So that the default invisible char is used again.
