From b520d2f93a907172d4eecf8f8d01b570ac422ef2 Mon Sep 17 00:00:00 2001 From: "a.kalmakhanov" Date: Sat, 16 Jul 2022 14:58:56 +0600 Subject: [PATCH 1/3] Added function to draw custom markers with Kotlin DSL Canvas API. FeatureId can be extended to hold info about a feature??? I added unused onFeatureClick, which can be latter implemented with pointer input, where it will check coordinates with offset? Features need to hold info about their coordinates? --- .../sciprog/maps/compose/FeatureBuilder.kt | 20 ++++++++++++++++++- .../centre/sciprog/maps/compose/MapFeature.kt | 11 +++++++++- .../centre/sciprog/maps/compose/MapView.kt | 7 +++++-- src/jvmMain/kotlin/Main.kt | 17 +++++++++++++--- .../centre/sciprog/maps/compose/MapViewJvm.kt | 6 +++++- 5 files changed, 53 insertions(+), 8 deletions(-) diff --git a/src/commonMain/kotlin/centre/sciprog/maps/compose/FeatureBuilder.kt b/src/commonMain/kotlin/centre/sciprog/maps/compose/FeatureBuilder.kt index 040a110..9a7e38f 100644 --- a/src/commonMain/kotlin/centre/sciprog/maps/compose/FeatureBuilder.kt +++ b/src/commonMain/kotlin/centre/sciprog/maps/compose/FeatureBuilder.kt @@ -3,9 +3,12 @@ package centre.sciprog.maps.compose import androidx.compose.runtime.Composable import androidx.compose.runtime.mutableStateMapOf import androidx.compose.runtime.snapshots.SnapshotStateMap +import androidx.compose.ui.geometry.Offset import androidx.compose.ui.geometry.Size import androidx.compose.ui.graphics.Color +import androidx.compose.ui.graphics.drawscope.DrawScope import androidx.compose.ui.graphics.vector.ImageVector +import centre.sciprog.maps.GmcBox typealias FeatureId = String @@ -15,7 +18,7 @@ interface FeatureBuilder { fun build(): SnapshotStateMap } -internal class MapFeatureBuilder(initialFeatures: Map) : FeatureBuilder { +internal class MapFeatureBuilder(initialFeatures: Map) : FeatureBuilder { private val content: SnapshotStateMap = mutableStateMapOf().apply { putAll(initialFeatures) @@ -41,6 +44,21 @@ fun FeatureBuilder.circle( id, MapCircleFeature(centerCoordinates.toCoordinates(), zoomRange, size, color) ) +fun FeatureBuilder.custom( + position: Pair, + id: FeatureId? = null, + customFeatureBuilder: DrawScope.(Offset) -> Unit, +) = addFeature(id, object : MapCustomFeature(position = position.toCoordinates()) { + override fun drawFeature(drawScope: DrawScope, offset: Offset) { + customFeatureBuilder(drawScope, offset) + } + + override fun getBoundingBox(zoom: Int): GmcBox { + return GmcBox(position.toCoordinates(), position.toCoordinates()) + } + +}) + fun FeatureBuilder.line( aCoordinates: Pair, bCoordinates: Pair, diff --git a/src/commonMain/kotlin/centre/sciprog/maps/compose/MapFeature.kt b/src/commonMain/kotlin/centre/sciprog/maps/compose/MapFeature.kt index 700e7aa..8b7defb 100644 --- a/src/commonMain/kotlin/centre/sciprog/maps/compose/MapFeature.kt +++ b/src/commonMain/kotlin/centre/sciprog/maps/compose/MapFeature.kt @@ -1,9 +1,11 @@ package centre.sciprog.maps.compose import androidx.compose.runtime.Composable +import androidx.compose.ui.geometry.Offset import androidx.compose.ui.geometry.Size import androidx.compose.ui.graphics.Color import androidx.compose.ui.graphics.ImageBitmap +import androidx.compose.ui.graphics.drawscope.DrawScope import androidx.compose.ui.graphics.painter.Painter import androidx.compose.ui.graphics.vector.ImageVector import androidx.compose.ui.graphics.vector.rememberVectorPainter @@ -31,6 +33,13 @@ class MapFeatureSelector(val selector: (zoom: Int) -> MapFeature) : MapFeature(d } +abstract class MapCustomFeature( + zoomRange: IntRange = defaultZoomRange, + val position: GeodeticMapCoordinates +) : MapFeature(zoomRange) { + abstract fun drawFeature(drawScope: DrawScope, offset: Offset) +} + class MapCircleFeature( val center: GeodeticMapCoordinates, zoomRange: IntRange = defaultZoomRange, @@ -68,7 +77,7 @@ class MapBitmapImageFeature( } -class MapVectorImageFeature ( +class MapVectorImageFeature( val position: GeodeticMapCoordinates, val painter: Painter, val size: Size, diff --git a/src/commonMain/kotlin/centre/sciprog/maps/compose/MapView.kt b/src/commonMain/kotlin/centre/sciprog/maps/compose/MapView.kt index ebd8483..8cc99ce 100644 --- a/src/commonMain/kotlin/centre/sciprog/maps/compose/MapView.kt +++ b/src/commonMain/kotlin/centre/sciprog/maps/compose/MapView.kt @@ -21,6 +21,7 @@ expect fun MapView( computeViewPoint: (canvasSize: DpSize) -> MapViewPoint, features: Map, onClick: MapViewPoint.() -> Unit = {}, + onFeatureClick: (FeatureId) -> Unit = {}, //TODO consider replacing by modifier config: MapViewConfig = MapViewConfig(), modifier: Modifier = Modifier.fillMaxSize(), @@ -32,13 +33,14 @@ fun MapView( initialViewPoint: MapViewPoint, features: Map = emptyMap(), onClick: MapViewPoint.() -> Unit = {}, + onFeatureClick: (FeatureId) -> Unit = {}, config: MapViewConfig = MapViewConfig(), modifier: Modifier = Modifier.fillMaxSize(), buildFeatures: @Composable (FeatureBuilder.() -> Unit) = {}, ) { val featuresBuilder = MapFeatureBuilder(features) featuresBuilder.buildFeatures() -
