Dynamic Search Box 1.0

KPF_CB was completely rewritten to work with mouse clicks and for Matlab R2011b. Currently it does not work with other releases. I haven't really looked into why yet, so I have included the original 'KPF_CB' and renamed it 'Original_KPF_CB' for compatibility.The new KPF_CB also heavily relies on Java. The Java part was made possible by Yair Altman and his 'findjobj'.From the help file,% a key press callback function for an edit box%% Description% KPF_CB() is a key press callback function for an edit box. This% callback creates a dynamically changing listbox under or above the% edit box (depending on space available). The contents of the listbox% change depending on the keys pressed. This callback may be useful% where very large lists are encountered and are difficult to sort% through, or may act as a search box.%% Syntax% set(edit_h,'KeyPressFcn', ...% {@KPF_CB,jedit_h,slider_h,fig_h,list,func})%% Arguments% edit_h - handle of the edit box to which KPF_CB is applied% jedit_h - handle of the java component of the edit box% slider_h - handle of the slider, if none, leave empty []% fig_h - handle of the figure of the edit box% list - list of selectable items% func - function to evaluate after 'return', or 'escape' key is% pressed or item in listbox is 'opened', if this is not needed,% leave empty [] or do not include in edit box 'KeyPressFcn'% callback%% Other Functionality% - KPF_CB incorporates the functionality of many special keys% including, backspace, delete, escape, insert, end, shift, return,% arrow keys, and space.% - Arrow keys allow the user to cycle left to right across the edit% box and continue typing with a dynamically changing listbox. They% also allow the user to scroll through the list box up and down.% - The 'return' key will either select the closest match to the% contents of the listbox from the contents of the edit box, or if% the arrow keys were previously used to cycle through the listbox,% then whichever item is currently highlighted will be selected. This% selected word will then appear in the edit box, and the listbox will% be deleted.% - Other keys behave as expected% - If an item in the listbox is clicked, the edit box will display% the item clicked on, but the contents of the listbox will remain the% same. If an item in the listbox is opened (i.e. double-clicked),% this will have the same effect as the 'return' key, but for the item% clicked on.% - A slider can be used with this function. For example, if multiple% edit boxes were placed on a panel with a slider, the listbox would% change size depending on the position of the edit box and slider.% - The optional function to evaluate after 'return', or 'escape' key% is pressed or item in listbox is 'opened' allows for immediate% function evaluation without needing a 'push button'%% Example% list = cell(26,26,26);% for i1 = 1:26% for i2 = 1:26% for i3 = 1:26% list{i1,i2,i3} = [char(64+i1) char(64+i2) char(64+i3)];% end% end% end% list = reshape(list,numel(list),1);% scrnsz = get(0,'ScreenSize');% fig_h = figure('MenuBar','none','Resize','off', ...% 'Position',[scrnsz(3)/2-100 scrnsz(4)/2-100 200 200]);% edit_h = uicontrol('Style','edit','Position',[6 170 190 25]);% jedit = java(findjobj(edit_h));% jedit_h = handle(jedit,'CallbackProperties');%% set(edit_h,'KeyPressFcn',{@KPF_CB,jedit_h,[],fig_h,list,@my_fun})% set(jedit_h,'MouseReleasedCallback',{@KPF_MR_CB,edit_h}, ...% 'MousePressedCallback',{@KPF_MP_CB,edit_h})%% function my_fun% get(edit_h,'String')% end%% Notes% - In order to close the listbox an item must be selected, by either% pressing either the 'escape' or 'return' keys or 'opening' an item in% the listbox% - This function makes use of the edit box user data variable% - Java is used extensively% - This function is not bug free yet, but usually hitting 'backspace'% or 'delete' enough times will clear whatever my function thinks is in% there% Version : 1.1 (10/06/2011)% Author : Nate Jensen% Created : 09/21/2011% History :% - v1.0 (09/21/2011) : initial release% - v1.1 (10/06/2011) : added java component to enable mouse clicks
