指定影响整个图形的视觉特性。有几个内置主题可以使用或自由修改。
可以覆写以下特性通过使用 QAbstract3DSeries 特性以按系列明确设置它们: baseColors , baseGradients ,和 colorStyle .
可以从新创建主题使用 ThemeUserDefined 枚举值。使用默认构造函数创建主题会产生新的用户定义主题。
The following table lists the properties controlled by themes and the default values for ThemeUserDefined .
创建内置主题不做任何修改:
Q3DTheme *theme = new Q3DTheme(Q3DTheme::ThemeQt);
创建内置主题并修改一些特性:
Q3DTheme *theme = new Q3DTheme(Q3DTheme::ThemeQt); theme->setBackgroundEnabled(false); theme->setLabelBackgroundEnabled(false);
创建用户定义主题:
Q3DTheme *theme = new Q3DTheme(); theme->setAmbientLightStrength(0.3f); theme->setBackgroundColor(QColor(QRgb(0x99ca53))); theme->setBackgroundEnabled(true); theme->setBaseColor(QColor(QRgb(0x209fdf))); theme->setColorStyle(Q3DTheme::ColorStyleUniform); theme->setFont(QFont(QStringLiteral("Impact"), 35)); theme->setGridEnabled(true); theme->setGridLineColor(QColor(QRgb(0x99ca53))); theme->setHighlightLightStrength(7.0f); theme->setLabelBackgroundColor(QColor(0xf6, 0xa6, 0x25, 0xa0)); theme->setLabelBackgroundEnabled(true); theme->setLabelBorderEnabled(true); theme->setLabelTextColor(QColor(QRgb(0x404044))); theme->setLightColor(Qt::white); theme->setLightStrength(6.0f); theme->setMultiHighlightColor(QColor(QRgb(0x6d5fd5))); theme->setSingleHighlightColor(QColor(QRgb(0xf6a625))); theme->setWindowColor(QColor(QRgb(0xffffff)));
创建内置主题并在设置后修改一些特性:
Q3DBars *graph = new Q3DBars(); graph->activeTheme()->setType(Q3DTheme::ThemePrimaryColors); graph->activeTheme()->setBaseColor(Qt::red); graph->activeTheme()->setSingleHighlightColor(Qt::yellow);
