You can assing empty list to Pane to make it empty <pre><code>Panes = [] </code></pre> but you will lost all added panes forever. Maybe you should make seperated list for keyboard panes and than draw only this list. EDIT: By the way: You use one variable <code>myScreen</code> to both screens - when you run <code>myScreen = Screen(...)</code> you create new screen but loose access to previous screen. Using <code>Screen = pygame.display.set_mode((1366,768), 0, 32); self.screen = Screen</code> to clear screen is waste of time and memories. You need only <code>self.screen.fill((white))</code> You use <code>Screen</code> name as class name and as variable in some functions. You can have accidentally name conflict. EDIT: Full working example how code could look like: I use one <code>self.screen</code> so window isn't created/deleted everytime. You can press "ESC" key to show/hide keyboard. <pre><code>import pygame import sys #---------------------------------------------------------------------- WHITE = (255,255,255) BLACK = (0 ,0 ,0 ) #--------------------------- MAIN_BUTTON = 2 KEYBOARD = True WORDS = False #---------------------------------------------------------------------- class Pane(): def __init__(self, textToDisplay, coordinates, screen): self.textToDisplay = textToDisplay self.coordinates = coordinates self.screen = screen self.font = pygame.font.SysFont('Palace Script MT', 25) #--------------------------- def coordinates(self): return self.coordinates #--------------------------- def text(self): return self.textToDisplay #--------------------------- def drawPane(self): textCoords = self.coordinates self.screen.blit(self.font.render(self.textToDisplay, True, BLACK), textCoords) pygame.draw.rect(self.screen, BLACK, self.coordinates, 2) #---------------------------------------------------------------------- class Application(): NoOfPanes = 0 NoOfKeys = 0 Panes = [] Keys = [] paneLocs = [(583, 334, 300, 150), (633, 150, 200, 125), (633, 600, 200, 125), (350, 360, 200, 100), (925, 360, 200, 100), (1000, 150, 150, 100), (275, 150, 150, 100), (275, 600, 150, 100), (1000, 600, 150, 100), (75, 350, 200, 100), (0, 668, 200, 100) ] keyboardPaneLocs = [(0, 100, 100, 100), (0, 200, 100, 100), (0, 300, 100, 100), (0, 400, 100, 100) ] #--------------------------- def __init__(self): pygame.init() pygame.display.set_caption('Box Test') self.font = pygame.font.SysFont('Arial', 25) self.screen = pygame.display.set_mode((1366,768), 0, 32) self.show_panes = True self.show_keyboard = False self.createPanes() self.createKeyboard() #--------------------------- def close(self): print "pygame quit" pygame.quit() sys.exit() #--------------------------- def createPanes(self): self.addPane("1", WORDS) self.addPane("2", WORDS) self.addPane("3", WORDS) self.addPane("4", WORDS) self.addPane("5", WORDS) self.addPane("6", WORDS) self.addPane("7", WORDS) self.addPane("8", WORDS) self.addPane("9", WORDS) self.addPane("10", WORDS) self.addPane("Keyboard", WORDS) #--------------------------- def createKeyboard(self): self.addPane("A", KEYBOARD) self.addPane("B", KEYBOARD) self.addPane("C", KEYBOARD) #--------------------------- def addPane(self, textToDisplay, keyboardFlag): if (not keyboardFlag) and (self.NoOfPanes > 11): print("Limit Reached") else: print(int(self.NoOfPanes)) if keyboardFlag: self.Keys.append(Pane(textToDisplay, self.keyboardPaneLocs[self.NoOfKeys], self.screen)) self.NoOfKeys += 1 else: self.Panes.append(Pane(textToDisplay, self.paneLocs[self.NoOfPanes], self.screen)) self.NoOfPanes += 1 #--------------------------- def drawPanes(self): for Pane in self.Panes: Pane.drawPane() #--------------------------- def drawKeyboard(self): for Key in self.Keys: Key.drawPane() #--------------------------- def mousePosition(self, event): if event.type == MAIN_BUTTON: self.Pos = pygame.mouse.get_pos() return MAIN_BUTTON else: return False #--------------------------- def mouseDown(self): posx,posy = pygame.mouse.get_pos() textToReturn = "Nothing selected" if self.show_panes: for Pane in self.Panes: paneCoords = Pane.coordinates print(str(paneCoords[0]) + ":" + str(paneCoords[1]) + ":" + str(paneCoords[2]) + ":" + str(paneCoords[3])) if (paneCoords[0] <= posx <= paneCoords[0]+paneCoords[2]) and (paneCoords[1] <= posy <= paneCoords[1]+paneCoords[3]): textToReturn = Pane.text() elif self.show_keyboard: for Pane in self.Keys: paneCoords = Pane.coordinates print(str(paneCoords[0]) + ":" + str(paneCoords[1]) + ":" + str(paneCoords[2]) + ":" + str(paneCoords[3])) if (paneCoords[0] <= posx <= paneCoords[0]+paneCoords[2]) and (paneCoords[1] <= posy <= paneCoords[1]+paneCoords[3]): textToReturn = Pane.text() return textToReturn #--------------------------- def run(self): clock = pygame.time.Clock() RUNNING = True while RUNNING: #

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
