From dc53baaaf65943c6768e3ad209129609334133e8 Mon Sep 17 00:00:00 2001 From: Bjørn Lindeijer Date: Sat, 16 Dec 2006 23:18:55 +0000 Subject: Subclassed ShopListBox from ListBox to get rid of some duplicated code, and fixed a problem with scrolling to the current selection. Also aligned the text a bit better and put the price in parenthesis. --- src/gui/shoplistbox.cpp | 138 +++++++++++++++++------------------------------- 1 file changed, 49 insertions(+), 89 deletions(-) (limited to 'src/gui/shoplistbox.cpp') diff --git a/src/gui/shoplistbox.cpp b/src/gui/shoplistbox.cpp index 61abff35..f5581323 100644 --- a/src/gui/shoplistbox.cpp +++ b/src/gui/shoplistbox.cpp @@ -34,11 +34,10 @@ #include "../graphics.h" -const int ITEM_SPRITE_HEIGHT = 32; +const int ITEM_ICON_SIZE = 32; ShopListBox::ShopListBox(gcn::ListModel *listModel): - gcn::ListBox(listModel), - mMousePressed(false), + ListBox(listModel), mPlayerMoney(0) { mRowHeight = getFont()->getHeight(); @@ -46,105 +45,97 @@ ShopListBox::ShopListBox(gcn::ListModel *listModel): } ShopListBox::ShopListBox(gcn::ListModel *listModel, ShopItems *shopListModel): - gcn::ListBox(listModel), - mMousePressed(false), + ListBox(listModel), mPlayerMoney(0), mShopItems(shopListModel) { - mRowHeight = (getFont()->getHeight() > ITEM_SPRITE_HEIGHT ? - getFont()->getHeight() : ITEM_SPRITE_HEIGHT); + mRowHeight = std::max(getFont()->getHeight(), ITEM_ICON_SIZE); mPriceCheck = true; } - void ShopListBox::setPlayersMoney(int money) { mPlayerMoney = money; } -void ShopListBox::draw(gcn::Graphics *graphics) +void ShopListBox::draw(gcn::Graphics *gcnGraphics) { - if (mListModel == NULL) { + if (!mListModel) return; - } + + Graphics *graphics = static_cast(gcnGraphics); graphics->setFont(getFont()); // Draw the list elements - for (int i = 0, y = 0; i < mListModel->getNumberOfElements(); ++i, y += mRowHeight) + for (int i = 0, y = 0; + i < mListModel->getNumberOfElements(); + ++i, y += mRowHeight) { - graphics->setColor(gcn::Color(0xffffff)); - if (mShopItems != NULL) + gcn::Color backgroundColor = gcn::Color(0xffffff); + + if (i == mSelected) + { + backgroundColor = gcn::Color(110, 160, 255); + } + else if (mShopItems && + mPlayerMoney < mShopItems->at(i).price && mPriceCheck) { - if(mPlayerMoney < mShopItems->at(i).price && mPriceCheck) - { - graphics->setColor(gcn::Color(0x919191)); - } + backgroundColor = gcn::Color(0x919191); } + + graphics->setColor(backgroundColor); graphics->fillRectangle(gcn::Rectangle(0, y, getWidth(), mRowHeight)); - if (mShopItems) - dynamic_cast(graphics)->drawImage(mShopItems->at(i).image, 1, y); - graphics->drawText(mListModel->getElementAt(i), ITEM_SPRITE_HEIGHT, y); - } - // Draw rectangle below the selected list element and the list element - // not shown. - if (mSelected >= 0) { - graphics->setColor(gcn::Color(110, 160, 255)); - graphics->fillRectangle(gcn::Rectangle(0, mRowHeight * mSelected, - getWidth(), mRowHeight)); if (mShopItems) - dynamic_cast(graphics)->drawImage( - mShopItems->at(mSelected).image, 1, mRowHeight * mSelected); - graphics->drawText(mListModel->getElementAt(mSelected), - ITEM_SPRITE_HEIGHT, mRowHeight * mSelected); + { + graphics->drawImage(mShopItems->at(i).image, 1, y); + } + graphics->drawText(mListModel->getElementAt(i), ITEM_ICON_SIZE + 5, + y + (ITEM_ICON_SIZE - getFont()->getHeight()) / 2); } } void ShopListBox::setSelected(int selected) { - gcn::ListBox::setSelected(selected); - if (mListModel != NULL) + if (!mListModel) { - gcn::BasicContainer *par = getParent(); - if (par == NULL) - { - return; - } - - gcn::Rectangle scroll; + mSelected = -1; + } + else + { + // Update mSelected with bounds checking + mSelected = std::min(mListModel->getNumberOfElements() - 1, + std::max(-1, selected)); - if (mSelected < 0) + gcn::BasicContainer *parent = getParent(); + if (parent) { - scroll.y = 0; + gcn::Rectangle scroll; + scroll.y = (mSelected < 0) ? 0 : mRowHeight * mSelected; + scroll.height = mRowHeight; + parent->showWidgetPart(this, scroll); } - else - { - scroll.y = mRowHeight * mSelected; - } - - scroll.height = mRowHeight; - par->showWidgetPart(this, scroll); } + fireSelectionChangedEvent(); } void ShopListBox::mousePress(int x, int y, int button) { - - bool enoughMoney = false; if (button == gcn::MouseInput::LEFT && hasMouse()) { - if (mShopItems) + bool enoughMoney = false; + + if (mShopItems && mPriceCheck) { - if(mPlayerMoney >= mShopItems->at(y / mRowHeight).price) + if (mPlayerMoney >= mShopItems->at(y / mRowHeight).price) enoughMoney = true; } else // Old Behaviour + { enoughMoney = true; - - if (!mPriceCheck) - enoughMoney = true; + } if (enoughMoney) { @@ -155,40 +146,9 @@ void ShopListBox::mousePress(int x, int y, int button) } } -void ShopListBox::mouseRelease(int x, int y, int button) -{ - gcn::ListBox::mouseRelease(x, y, button); - - mMousePressed = false; -} - -void ShopListBox::mouseMotion(int x, int y) -{ - gcn::ListBox::mouseMotion(x, y); - - // Pretend mouse is pressed continuously while dragged.
