    <p>So basically I have a two separate screens that I want displayed. One that has 11 Panes displayed on the screen at one time and once I click on a Pane named keyboard it should clear the screen and set up 36 Panes which should display a keyboard (for test purposes I only used three panes).</p> <p>My problem is that once I click on keyboard it does clear the screen and display the 3 test panes how it also display's my other 10 panes that come from the first page.</p> <p><strong>Example:</strong> This is fine to start with: <img src="https://i.stack.imgur.com/5ciSM.png" alt="Fine Display"></p> <p>This is not fine. (A, B And C should be displayed but the rest shouldn't): <img src="https://i.stack.imgur.com/Oi3Pb.png" alt="Not Fine"></p> <p>Here is the code:</p> <pre><code>import pygame import sys white = (255,255,255) black = (0,0,0) objs = [] 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) Screen = pygame.display.set_mode((1366,768), 0, 32) self.screen = Screen self.screen.fill((white)) 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) pygame.display.update() class Screen(): NoOfPanes = 0 Panes = [] 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) Screen = pygame.display.set_mode((1366,768), 0, 32) self.screen = Screen self.screen.fill((white)) pygame.display.update() def addPane(self, textToDisplay, keyboardFlag): if (not keyboardFlag) and (self.NoOfPanes &gt; 11): print("Limit Reached") else: print(int(self.NoOfPanes)) if keyboardFlag: newPane = Pane(textToDisplay, self.keyboardPaneLocs[self.NoOfPanes], Screen) else: newPane = Pane(textToDisplay, self.paneLocs[self.NoOfPanes], Screen) self.Panes.append(newPane) self.NoOfPanes = self.NoOfPanes + 1 pygame.display.update() def drawPanes(self): for Pane in self.Panes: Pane.drawPane() def mousePosition(self): global clickPos global releasePos for event in pygame.event.get(): if event.type == MAIN_BUTTON: self.Pos = pygame.mouse.get_pos() return MAIN_BUTTON else: return False def mouseDown(self, posx, posy): textToReturn = "Nothing selected" for Pane in self.Panes: paneCoords = Pane.coordinates print(str(paneCoords[0]) + ":" + str(paneCoords[1]) + ":" + str(paneCoords[2]) + ":" + str(paneCoords[3])) if (paneCoords[0] &lt;= posx &lt;= paneCoords[0]+paneCoords[2]) and (paneCoords[1] &lt;= posy &lt;= paneCoords[1]+paneCoords[3]): textToReturn = Pane.text() return textToReturn def displayKeyboard(self): self.addPane("A", KEYBOARD) self.addPane("B", KEYBOARD) self.addPane("C", KEYBOARD) def clearScreen(self): Screen = pygame.display.set_mode((1366,768), 0, 32) self.screen = Screen self.screen.fill((white)) if __name__ == '__main__': myScreen = Screen() myScreen.addPane("1", WORDS) myScreen.addPane("2", WORDS) myScreen.addPane("3", WORDS) myScreen.addPane("4", WORDS) myScreen.addPane("5", WORDS) myScreen.addPane("6", WORDS) myScreen.addPane("7", WORDS) myScreen.addPane("8", WORDS) myScreen.addPane("9", WORDS) myScreen.addPane("10", WORDS) myScreen.addPane("Keyboard", WORDS) myScreen.drawPanes() while True: ev = pygame.event.get() for event in ev: if event.type == pygame.MOUSEBUTTONUP: posx,posy = pygame.mouse.get_pos() textSelected = myScreen.mouseDown(posx, posy) print(textSelected) if textSelected == "Keyboard": myScreen = Screen() myScreen.clearScreen() myScreen.displayKeyboard() myScreen.drawPanes() for event in pygame.event.get(): if event.type == pygame.QUIT: pygame.quit(); sys.exit(); </code></pre> <p>I think the problem that I am facing is that all of these panes are being added to the list <code>Panes = []</code>. How can I make sure that this list is clear before I display the new panes through the use of the function <code>def drawPanes(self):</code> </p> <p>Don't take my word for it as it is just an assumption and I am well and truly stuck. (Any help is appreciated.)</p>

    1. COI don't have PyGame to test here, maybe if you try self.Panes = [] at the end of the clearScreen function. Be careful with members you declare at the class level, I had bad surprises especially in Python 2. You'd better have self.Panes = [] in your __init__ function.

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.
