102 \since 5.0 -

103 \inherits Item -

104 \ingroup qtquick-effects -

105 \brief Renders a \l {Qt Quick} item into a texture and displays it. -

106 -

107 The ShaderEffectSource type renders \l sourceItem into a texture and -

108 displays it in the scene. \l sourceItem is drawn into the texture as though -

109 it was a fully opaque root item. Thus \l sourceItem itself can be -

110 invisible, but still appear in the texture. -

111 -

112 ShaderEffectSource can be used as: -

113 \list -

114 \li a texture source in a \l ShaderEffect. -

115 This allows you to apply custom shader effects to any \l {Qt Quick} item. -

116 \li a cache for a complex item. -

117 The complex item can be rendered once into the texture, which can -

118 then be animated freely without the need to render the complex item -

119 again every frame. -

120 \li an opacity layer. -

121 ShaderEffectSource allows you to apply an opacity to items as a group -

122 rather than each item individually. -

123 \endlist -

131 Rectangle { -

132 width: 200 -

133 height: 100 -

134 gradient: Gradient { -

135 GradientStop { position: 0; color: "white" } -

136 GradientStop { position: 1; color: "black" } -

137 } -

138 Row { -

139 opacity: 0.5 -

140 Item { -

141 id: foo -

142 width: 100; height: 100 -

143 Rectangle { x: 5; y: 5; width: 60; height: 60; color: "red" } -

144 Rectangle { x: 20; y: 20; width: 60; height: 60; color: "orange" } -

145 Rectangle { x: 35; y: 35; width: 60; height: 60; color: "yellow" } -

146 } -

147 ShaderEffectSource { -

148 width: 100; height: 100 -

149 sourceItem: foo -

150 } -

151 } -

152 } -

153 \endqml -

154 \endtable -

155 -

156 The ShaderEffectSource type does not redirect any mouse or keyboard -

157 input to \l sourceItem. If you hide the \l sourceItem by setting -

158 \l{Item::visible}{visible} to false or \l{Item::opacity}{opacity} to zero, -

159 it will no longer react to input. In cases where the ShaderEffectSource is -

160 meant to replace the \l sourceItem, you typically want to hide the -

161 \l sourceItem while still handling input. For this, you can use -

162 the \l hideSource property. -

163 -

164 \note If \l sourceItem is a \l Rectangle with border, by default half the -

165 border width falls outside the texture. To get the whole border, you can -

166 extend the \l sourceRect. -

167 -

168 \note The ShaderEffectSource relies on FBO multisampling support -

169 to antialias edges. If the underlying hardware does not support this, -

170 which is the case for most embedded graphics chips, edges rendered -

171 inside a ShaderEffectSource will not be antialiased. One way to remedy -

172 this is to double the size of the effect source and render it with -

173 \c {smooth: true} (this is the default value of smooth). -

174 This will be equivalent to 4x multisampling, at the cost of lower performance -

175 and higher memory use. -

176 -

177 \warning In most cases, using a ShaderEffectSource will decrease -

178 performance, and in all cases, it will increase video memory usage. -

179 Rendering through a ShaderEffectSource might also lead to lower quality -

180 since some OpenGL implementations support multisampled backbuffer, -

181 but not multisampled framebuffer objects. -

599 other parts of the scene. -
